The study of color expanded rapidly in the 20th century. With this expansion came fragmentation, as philosophers, physicists, physiologists, psychologists, and others explored the subject in vastly different ways. There are at least two ways in which the study of color became contentious. The first was with regard to the definitional question: what is color? The second was with the location question: are colors inside the head or out in the world? In this chapter, we summarize the most prominent answers (...) that color scientists and philosophers gave to the definitional and location questions in the 20th century. We identify some of the different points at which their work intersected, as well as the most prominent schisms between them. One overarching theme of the chapter is the surprising proliferation of different views on color. Whereas some assume that progress in science must take the form of convergence, the 20th century history of color exhibited a marked divergence in views. This chapter leaves it an open question whether an ultimate unification of views is possible, or whether the only thing that ties together the study of “color” is the shared inheritance of a word.

Most things we see look colored to us. But what is color? Where, if anywhere, is it? Why do we see it? When do we see it correctly? And how should we go about answering these surprisingly difficult questions? This essay surveys philosophical work on color and color perception.

I argue against a class of philosophical views of color perception, especially insofar as such views posit the existence of color sensations. I argue against the need to posit such nonconceptual mental intermediaries between the stimulus and the eventual conceptualized perceptual judgment. Central to my arguments are considerations of certain color illusions. Such illusions are best explained by reference to high-level, conceptualized knowledge concerning, for example, object identity, likely lighting conditions, and material composition of the distal stimulus. Such explanations obviate (...) the need to appeal to nonconceputal mental links in the causal chains eventuating in conceptualized color discriminations. (shrink)

This essay is an introduction to the Routledge Handbook of Philosophy of Colour. Why has the examination of many different aspects of colour been a prominent feature in philosophy, to such an extent that the topic is worthy of a handbook? Here are two related answers. First, colours are exceedingly familiar, seemingly simple features that become enigmatic under scrutiny, and they are difficult to capture in any familiar-sounding, unsophisticated theory. Second, through colour one can confront (...) various problems that span the breadth of philosophy, including problems pertaining to perception, the mind-body relation, the nature of science, scepticism, vagueness, meta-ethics, and aesthetics. In this introduction we elaborate and guide the reader to the essays in the rest of this volume. (shrink)

From David Hume's famous puzzle about 'the missing shade of blue' to current research into the science of colour, the topic of colour is an incredibly fertile region of study and debate, cutting across philosophy of mind, epistemology, metaphysics and aesthetics as well as psychology. Debates about the nature of our experience of colour and the nature of colour itself are central to contemporary discussion and argument in philosophy of mind and psychology, and (...) class='Hi'>philosophy of perception. This outstanding Handbook contains twenty-nine specially commissioned contributions by leading philosophers and examines the most important aspects of philosophy of colour. It is organised into six parts: The Importance of Colour to Philosophy The Science and Spaces of Colour Colour Phenomena Colour Ontology Colour Experience and Epistemology Language, Categories and Thought. The Routledge Handbook of Philosophy of Colour is essential reading for students and researchers in philosophy of mind and psychology, epistemology, metaphysics and aesthetics, as well as for those interested in conceptual issues in the psychology of colour.

I outline five issues in philosophy of colour that deserve greater attention and provide skeletal frameworks for how future work on these topics could be carried out. The issues are: colour and metaphilosophy, colour and artistic practice, colour and virtual/augmented reality, colour and imagination, and colour and the predictive mind. Some of these issues have been a focus of important recent works. Thus, colour conjoined with each of metaphilosophy, artistic practice and imagination (...) have all been examined in at least a few recent publications – see below for references. It is clear, however, that these recent works are signals that there is much still to be done. By contrast, while at present there is a great deal of interest in the predictive mind, the intersection of colour and the predictive mind is vastly underexplored. This is despite the fact that the philosophy and science of colour are rather developed disciplines. Finally, while there have been some very important recent works on virtual and augmented reality, the significance of colour for these studies has yet to be examined. It is my hope that after reading this article readers are convinced not only that the philosophy of colour has a rich, recent history, but also a very bright future. (shrink)

Book Review of Naomi Zack's Women of Color and Philosophy.

Philosophy is in its fourth millennium but this collection is the first of its kind. Twelve contemporary women of color who are American academic philosophers consider the methods and subjects of the discipline from perspectives partly informed by their experiences as African American, Asian American, Latina, Mixed Race and Native American.

Is color real or illusory, mind independent or mind dependent? Does seeing in color give us a true picture of external reality? The metaphysical debate over color has gone on at least since the seventeenth century. In this book, M. Chirimuuta draws on contemporary perceptual science to address these questions. Her account integrates historical philosophical debates, contemporary work in the philosophy of color, and recent findings in neuroscience and vision science to propose a novel theory of the relationship between (...) color and physical reality. -/- Chirimuuta offers an overview of philosophy’s approach to the problem of color, finds the origins of much of the familiar conception of color in Aristotelian theories of perception, and describes the assumptions that have shaped contemporary philosophy of color. She then reviews recent work in perceptual science that challenges philosophers’ accounts of color experience. Finally, she offers a pragmatic alternative whereby perceptual states are understood primarily as action-guiding interactions between a perceiver and the environment. The fact that perceptual states are shaped in idiosyncratic ways by the needs and interests of the perceiver does not render the states illusory. Colors are perceiver-dependent properties, and yet our awareness of them does not mislead us about the world. Colors force us to reconsider what we mean by accurately presenting external reality, and, as this book demonstrates, thinking about color has important consequences for the philosophy of perception and, more generally, for the philosophy of mind.

In On the Genealogy of Color , Zed Adams challenges widely held philosophical views about the nature of color, exploring the relevance of the history of color science for contemporary debates in color realism/anti-realism and philosophy of mind. Adams argues that the two sides of the contemporary debate on the problem of color realism, Cartesian anti-realism and Oxford realism, are both predicated on an assumption that the concept of color perception is ahistorical and unrevisable. Adams takes issue with this (...) premise and traces the development of theories of color in order to undermine this assumption and open up the conversation about our perception of color. This book makes a significant contribution to recent debates on philosophical methodology by demonstrating the efficacy of using the genealogical method to explore philosophical concepts, and will appeal to philosophers of perception, philosophers of mind, and metaphysicians.

What is colour vision for? In the popular imagination colour vision is for “seeing the colours” — adding hue to the achromatic world of shape, depth and motion. On this view colour vision plays little more than an ornamental role, lending glamour to an otherwise monochrome world. This idea has guided much theorising about colour within vision science and philosophy. However, we argue that a broader approach is needed. Recent research in the psychology of (...) class='Hi'>colour demonstrates that colour vision is integral to a variety of visual processes, helping us to perform many types of visual tasks. We discuss some of this research and consider its implications for philosophical theories of colour. (shrink)

Our modern scientific explanation of colour as a subjective impression has replaced a ‘pre-theoretical’ notion of colour as an intrinsic property of objects, which was mainstream in ancient thought. Why have we lost such pre-theoretical notion, and what have we lost by losing it? I argue that most ancient Greek philosophers exploited this pre-theoretical assumption – one that was obvious to them – in terms and ways that are still worthy of attention in the context of contemporary (...) class='Hi'>philosophy of colour. I offer an in-depth analysis of the theories of a number of early Greek philosophers, as well as of Plato in the Timaeus, showing that they tend to share the idea that colour is an essential property of external bodies and therefore plays a causal role in perception. Then I focus on a comparison between Democritus’ stance and Aristotle’s in order to highlight a significant contrast between the two. Democritus' theory is an exception in ancient thought because it traces the colour phenomenon back to a refraction of atmospheric light through atomic aggregates. Aristotle, instead, posits the presence of colour and light in the bodies themselves. Finally, I interpret Aristotle's account as the most complex attempt in ancient thought to weld together what we call the ‘manifest image’ of colour and its ‘scientific image’. (shrink)

Goethe carried out an enormous number of experiments before criticizing Newton's theory of light and colours in the Farbenlehre (1810). He managed to show that Newton's reasoning is based on a rather narrow choice of experiments, in which parameters such as the distance between the prism and the screen are fixed arbitrarily: Newton's famous spectrum (with its green centre) occurs only at a specific distance. Once you reduce the distance, the green centre disappears, and you see the two border spectra (...) instead. Newton can of course explain these border spectra; but things can be explained just as well the other way around: Then you start with a theory based on the two border spectra in order to derive the Newtonian spectrum. Both accounts fit many data (available in Newton and Goethe's days) equally well. Thus by insisting that the step to theory is not forced upon us by "reason and experiments" alone (as Newton would have it), Goethe revealed our own free, creative contribution to theory construction. And surprisingly, his theory of the prismatic colours seems no worse off than Newton's, even taking into account additional criteria of theory choice, such as simplicity or elegance. (shrink)

Can the phenomenal character of perceptual experience be altered by the states of one's cognitive system, for example, one's thoughts or beliefs? If one thinks that this can happen then one thinks that there can be cognitive penetration of perceptual experience; otherwise, one thinks that perceptual experience is cognitively impenetrable. I claim that there is one alleged case of cognitive penetration that cannot be explained away by the standard strategies one can typically use to explain away alleged cases. The case (...) is one in which it seems subjects' beliefs about the typical colour of objects affects their colour experience. I propose a two-step mechanism of indirect cognitive penetration that explains how cognitive penetration may occur. I show that there is independent evidence that each step in this process can occur. I suspect that people who are opposed to the idea that perceptual experience is cognitively penetrable will be less opposed to the idea when they come to consider this indirect mechanism and that those who are generally sympathetic to the idea of cognitive penetrability will welcome the elucidation of this plausible mechanism.

Scholars of color have been instrumental in advancing nursing knowledge development but find limited spaces where one can authentically share their philosophical perspective. Although there is a call for antiracism in nursing and making way for more diverse and inclusive theories and philosophies, our voices remain at the margins of nursing theory and philosophy. In nursing philosophy, there continues to be a lack of racial diversity in those who are given the platform to share their scholarship. Five nurse (...) scholars of color attended the International Nursing Philosophy Conference in August 2022. We established a collective system of support by sharing our experiences as researchers, scholars, and educators with each other. The theory of emancipatory nursing praxis informed this process. In this dialogue, we reflected on what it is like to present at and attend predominantly white nursing conferences. We shared our experiences of how we exist as nurse scholars, our philosophical views, and our thoughts on how we create spaces where scholars of color can feel welcomed and acknowledged for their contributions to advancing nursing knowledge.

A survey of color science and color vision.

This book is a major contribution to the interdisciplinary project of investigating the true nature of color vision.

This piece contextualizes a discussion by liminal feminists on the identifiers ‘women of color’ and ‘Third World women’ that emerged from some uncomfortable and constructive conversations at the 2015 FEAST conference. I focus on concerns of marginalization and gatekeeping that are far too often reiterated within the uneasy racial dynamics among feminist philosophers.

This entry outlines physicalism about color, and objections to the effect that it cannot meet various desiderata on a metaphysics of color.

Colour fascinates all of us, and scientists and philosophers have sought to understand the true nature of colour vision for many years. In recent times, investigations into colour vision have been one of the main success stories of cognitive science, for each discipline within the field - neuroscience, psychology, linguistics, computer science and artificial intelligence, and philosophy - has contributed significantly to our understanding of colour. Evan Thompson's book is a major contribution to this interdisciplinary (...) project. Colour Vision provides an accessible review of the current scientific and philosophical discussions of colour vision. Thompson steers a course between the subjective and objective positions on colour, arguing for a relational account. This account develops a novel `ecological' approach to colour vision in cognitive science and the philosophy of perception. It is vital reading for all cognitive scientists and philosophers whose interests touch upon this central area. (shrink)

What is the experience of someone who is “colour‐blind” like? This paper presents the results of a study that uses qualitative research methods to better understand the lived experience of colour blindness.

More generally, the paper provides a case study in the nascent field (...) of experimental philosophy of experience. (shrink)

The article draws on critiques in political theory and morality to argue that womanism, a worldview rooted in Black women's lives and history, provides an alternative conceptual framework to prevailing Eurocentric thinking, for promoting socially just institutions of higher education. Presupposing a positioned, encultured, and embodied account of identity, womanism’s social change perspective holds transformative promise. It foregrounds Black women’s penchant for reaching solutions that promote communal balance, affirm one’s humanity and attend to the spiritual dimension (Phillips, 2006 Phillips, L. (...) (Ed.). (2006). The womanist reader. Routledge.[Crossref], [Google Scholar]). Directed first towards scholars of color, fostering inclusivity, communalist values and acknowledged intersectionality offers an ethic of the embodied self. As a corollary, it argues for a universal that recommends at least two guiding principles for a pedagogical philosophy. It is, first oriented towards a love of self and second towards placing all disciplines within a cultural-historical context. In the first claim, there is potential for nothing less than suspending the symbolic and ontological violence to one’s sense of belonging in academia. In the second claim, such an understanding can position scholars of color to actively re-narrate their fields. As illustrations, we focus on three academic fields of education, theology in higher education, and criminal justice. (shrink)

Much research on color representation and categorization has assumed that relations among color terms can be proxies for relations among color percepts. We test this assumption by comparing the mapping of color words with color appearances among different observer groups performing cognitive tasks: an invariance of naming task; and triad similarity judgments of color term and color appearance stimuli within and across color categories. Observer subgroups were defined by perceptual phenotype and photopigment opsin genotype analyses. Results suggest that individuals rely (...) on at least two different representational models of color experience: one lexical, conforming to the culture's normative linguistic representation, and another individual perceptual representation organizing each observer's color sensation experiences. Additional observer subgroup analyses suggest that perceptual phenotype variation within a language group may play a greater role in the shared color naming system than previously thought. A reexamination of color naming data in view of these findings may reveal influences on color naming important to current theories. (shrink)

C. L. Hardin led a recent development in the philosophical literature on color in which research from visual science is used to argue that colors are not properties of physical objects, but rather are mental processes. I defend J. J. C. Smart's physicalism, which claims that colors are physical properties of objects, against this attack. Assuming that every object has a single veridical (that is, nonillusory) color, it seems that physicalism must give a specification of veridical color in terms natural (...) to physics, independently of our interests. Hardin argues that since physicalism doesn't give us any such specification of veridical color, this view is false. However, this argument assumes a mistaken account of veridical color. I show physicalism can appeal to an alternative account, according to which veridical color is characterized in terms of favored conditions of perceptual access, independently of any specification of the physical nature of color.

Naomi Zack’s unique and important collection, Women of Color and Philosophy, brings together for the first time the voices of twelve philosophers who are women of color. She begins with the premise that the work of women of color who do philosophy in academe, but who do not write exclusively on issues of race, ethnicity, and gender, merits a collection of its own. It’s rare that women of color pursue philosophy in academic contexts; Zack counts at most (...) thirty among the ten thousand members of the American Philosophical Association. Women of color in philosophy often suffer an initial lack of credibility with colleagues and students, their success is often attributed to affirmative action, and the merit of their research is often questioned. They are expected to teach classes on race and gender, and asked to serve on endless committees vouching for the diversity of university programs and policies. But Zack’s collection is not about the philosophical import of these professional considerations. The idea underlying her anthology is that social identity is relevant to both philosophical activity and the production of ideas even when an author does not address race and gender. -/- This landmark volume is divided into three sections intended to reflect three critical themes: direct critiques of traditional academic philosophy; new and original applications of philosophical methods to social issues; and the fresh interpretation of traditional philosophy in ways that suggest new areas of study.

The standard adaptationist explanation of the presence of a sensory mechanism in an organism—that it detects properties useful to the organism—cannot be given for color vision. This is because colors do not exist. After arguing for this latter claim, I consider, but reject, nonadaptationist explanations. I conclude by proposing an explanation of how color vision could have adaptive value even though it does not detect properties in the environment.

Some, if not most, philosophy program admissions committee members assume that they can determine that one applicant will likely manifest a higher degree of philosophical skill than another applicant on the basis of differences between their materials. I challenge this assumption by explaining how applicants’ materials in significant measure reflect the racially unjust environment in which they manifest their philosophical skill. I explain how applicants’ racial-group membership in similar measure determines what these materials consist in.

This paper considers whether there can be any such thing as a naturalized metaphysics of color—any distillation of the commitments of perceptual science with regard to color ontology. I first make some observations about the kinds of philosophical commitments that sometimes bubble to the surface in the psychology and neuroscience of color. Unsurprisingly, because of the range of opinions expressed, an ontology of color cannot simply be read off from scientists’ definitions and theoretical statements. I next consider two alternative routes. (...) First, conceptual pluralism inspired by Mark Wilson's analysis of scientific representation. I argue that these findings leave the prospects for a naturalized color ontology rather dim. Second, I outline a naturalized epistemology of perception. I ask how the correctness and informativeness of perceptual states is understood by contemporary perceptual science. I argue that the detectionist ideal of correspondence should be replaced by the pragmatic ideal of usefulness. I argue that this result has significant implications for the metaphysics of color.

The papers comprising Zur Farbenlehre, best known portion of Goethe's writings on color and optics, appeared between 1808 and 1810. Portions of Zur Farbenlehre, translated by the painter Charles Lock Eastlake and frequently reprinted under the title Theory of Colours, achieved immediate notoriety because of Goethe's insistent questioning of Newton's methodology. Acknowledging no mentors except Theophrastus and the physicist Robert Boyle, Goethe compared the Newtonian theory of colors--indelicately, some think--to a once proud castle still revered long after it has fallen (...) into decay. The furor aroused by this intemperate analogy has not fully subsided yet. During the twentieth century Max Planck answered the impertinence with a vigorous ad hominem attack and Rudolph Carnap followed suit. We still lack a serious analysis of Goethe's color theories or his arguments against Newton. And the early vituperation seems quaint. Questioning Newton's methodology--or even his epistemology--is a legitimate activity and has even become commonplace. The 1840 edition of Eastlake's translation enjoys a perennial popularity among artists and a few perceptual psychologists, who have been allowed to monopolize for too long a book which is primarily a highly provocative inquiry in the philosophy of science. Someday an imaginative publisher may be inspired to make available more extensive translations of Goethe's copious writings on color, complemented by the type of careful editing, annotation and analysis which I. Bernard Cohen and Alexander Koyré provide for the writings of Newton. Until then one is grateful for Eastlake.--P. S. (shrink)

Scientists are often bemused by the efforts of philosophers essaying a theory of colour: colour science sports a huge array of facts and theories, and it is unclear to its practitioners what philosophy can or is trying to contribute. Equally, philosophers tend to be puzzled about how they can fit colour science into their investigations without compromising their own disciplinary identity: philosophy is supposed to be an a priori investigation; philosophers do not work in psychophysics (...) labs – not in their professional capacity, anyway.These inter-disciplinary barriers arise out of misunderstanding. Philosophers should not so much attempt to contribute to empirical theories of colour, as to formulate philosophical theories of colour. Philosophy is concerned with appearance and reality, object and property, function and representation, and other such fundamental categories of ontology and epistemology. Philosophical theories attempt to fit colour into these categories; such theories do not compete with colour science. However, fitting colour into philosophical theories means dealing with colour as it really is – and one cannot know what it is without consulting the psychologists. That is why philosophers need an up-to-date understanding of psychological theories of colour. (shrink)

Abstract: -/- We present a teaching activity, whose aim is to enhance students’ understanding of color perception by introducing them to intersubjective color variations among normal perceivers. The approach can be used in different disciplines, including biology, philosophy, psychology, physics, or statistics, for different purposes and with college students having various levels of sophistication and scientific training.

Physics tells us what is objectively there. It has no place for the colours of things. So colours are not objectively there. Hence, if there is such a thing at all, colour is mind-dependent. This argument forms the background to disputes over whether common sense makes a mistake about colours. It is assumed that..

Recent experimental work has shown that the truth-value judgments of color predications, i.e. utterances of the form “the leaves on my tree are green” or “these walls are brown,” are influenced by slight changes in the context of utterance (Hansen and Chemla 2013, Ziółkowski, 2021). Most explanations of this phenomenon focus on the semantics of color adjectives. However, it is not clear if these explanations do justice to the nuances of the empirical data on context-sensitivity of color predications (Ziółkowski, 2021). (...) In contrast to the adjectival explanations, Agustin Vicente (2015) has recently proposed that the context-sensitivity of color predications can be explained by invoking the polysemy of the noun. In this paper, we present the results of three studies designed to empirically test this hypothesis: a traditional survey experiment (Study 1), an exploratory correlational study inspired by the semantic integration paradigm (Study 2a), and a follow-up experiment (Study 2b) that was designed to mitigate possible shortcomings of Study 2a. The results of our studies present preliminary evidence against Vicente’s theory. (shrink)

The art of traditional painting and ceramic painting in China has a long tradition, in particular in understanding the role of color in the compositional and semantic structure. The principles of creating a color image have long been associated with national peculiarities of perception of shades and their combinations, as well as philosophical ideas. Technological features and properties of glazes imposed certain restrictions on the use of expressive possibilities of color by Chinese ceramic artists. The object of this research is (...) the works of Chinese painting and ceramics, the subject is the principles of color formation in these arts. Particular attention is paid to identifying similarities in approaches to color transfer in paintings and ceramics. The author's special contribution to the study of the problem is an attempt to characterize and compare the role of color in the art of Chinese painting and ceramic painting. The article defines a number of general principles of correlation and harmonization of colors in the two arts. The traditions of the color formation of works of various epochs are traced, the peculiarities of their evolution are established, the colors characteristic of painting and painting ceramics of different historical periods are revealed. The article examines the essence and symbolism of different colors, which are based on national philosophical and cultural ideas. The conclusion is made about the significance of the color image and color formation for the works of ceramics and painting in China. (shrink)

This article draws on the social theory of Theodor W. Adorno in order to critique the discourse of ‘color-blindness’ and articulate an alternative individualist ideal of racial justice. I begin by noting that Adorno’s criticism of law in Negative Dialectics anticipates arguments against color-blindness advanced in critical race theory. I then explicate Adorno’s understanding of law in relation to his broader account of social domination. Race can be situated within this account through the concept of ‘second nature’. The notion of (...) racial second nature elucidates the contradiction within color-blindness between formal equality and substantive inequality. As an alternative to the color-blind norm, I posit Adorno’s utopian ideal of emancipated individuality as an appropriate aspiration for racial justice. This ideal enables the jurisgenerative transformation of liberal rights concepts, which have at once enabled and constrained the struggle for racial equity. (shrink)

This article discusses sorrow in terms of its resistant possibilities. It describes bodies of color as ontological sites of sorrow in the context of racism and xenophobia. This sorrow, however, does not condemn these bodies to hopelessness and erasure. Rather, it may constitute a rupture with a present that fails to acknowledge racist and xenophobic practices. In addition, it connects sorrow to the kind of melancholia that bodies of color experience given their being-in-worlds that consider them unwanted, unworthy, and disposable. (...) By way of photographic analysis, this article also presents the notion of aesthetic unsettlement in order to point to coalitional possibilities across experiences and histories of woundedness, melancholia, and sorrow.

Modern color science finds its birth in the middle of the nineteenth century. Among the chief architects of the new color theory, the name of the polymath Hermann von Helmholtz stands out. A keen experimenter and profound expert of the latest developments of the fields of physiological optics, psychophysics, and geometry, he exploited his transdisciplinary knowledge to define the first non-Euclidean line element in color space, i.e., a three-dimensional mathematical model used to describe color differences in terms of color distances. (...) Considered as the first step toward a metrically significant model of color space, his work inaugurated researches on higher color metrics, which describes how distance in the color space translates into perceptual difference. This paper focuses on the development of Helmholtz’s mathematical derivation of the line element. Starting from the first experimental evidence which opened the door to his reflections about the geometry of color space, it will be highlighted the pivotal role played by the studies conducted by his assistants in Berlin, which provided precious material for the elaboration of the final model proposed by Helmholtz in three papers published between 1891 and 1892. Although fallen into oblivion for about three decades, Helmholtz’s masterful work was rediscovered by Schrödinger and, since the 1920s, it has provided the basis for all subsequent studies on the geometry of color spaces up to the present time.

There have been a number of criticisms, based on visual processes, of the Australian view that colour is an objective property of the world. These criticisms have led to subjective theories about colour. These visual processes (metamers, retinex theory, opponent processes, simultaneous contrast, colour constancy, subjective colours) have been examined and it is suggested that they do not carry their supposed critical weight against an objective theory. In particular, it is argued that metamers don’t occur in nature (...) and primate colour vision evolved without metamers. Thus normal colour vision occurs without the problem of metamers. This argument, in conjunction with evidence against the critical roles of opponent processes and retinex theory in colour vision, is taken to suggest that colour can be given a photon energy/wavelengthrealism explanation. This proposal allows an account of the many microstructural bases of colour generation put forward by Nassau (1983). It is argued that neither disjunctive realism or reflectance realism are adequate objective explanations of colour. (shrink)

This entry outlines relationalism, primitivism, and eliminativism about color and considers objections to each theory.

Drawing on remarks scattered through his writings, I argue that Leibniz has a highly distinctive and interesting theory of color. The central feature of the theory is the way in which it combines a nuanced subjectivism about color with a reductive approach of a sort usually associated with objectivist theories of color. After reconstructing Leibniz's theory and calling attention to some of its most notable attractions, I turn to the apparent incompatibility of its subjective and reductive components. I argue that (...) this apparent tension vanishes in light of his rejection of a widely accepted doctrine concerning the nature of bodies and their geometrical qualities. (shrink)
