According to naïve realist (or primitivist) theories of colour, colours are sui generis mind-independent properties. The question that I consider in this paper is the relationship of naïve realism to what Mark Johnston calls Revelation, the thesis that the essential nature of colour is fully revealed in a standard visual experience. In the first part of the paper, I argue that if naïve realism is true, then Revelation is false. In the second part of the paper, I defend naïve (...) realism against a number of objections.

The problem of the nature of color is typically put in terms of the following question about the intentional content of visual experiences: what’s the nature of the property we attribute to physical objects in virtue of our visual experiences of color? This problem has proven to be tenacious largely because it’s not clear what the constraints are for an answer. With no clarity about constraints, the proposed solutions range widely, the most common dividing into subjectivist (...) views which hold that attributed colors are mental properties or mental events} and a variety of realist views, which hold that colors are properties of physical objects. These realist views, in turn, divide into views that hold that attributed colors are dispositions of physical objects to produce color experiences (dispositionalism),° nondispositional relations between objects and perceivers (the relational view)," physical properties of physical objects (physicalism),‘ or sui generis properties of physical objects (primitivism and impressionism).‘ I’ll examine a proposed constraint which Mark Johnston (1992) calls Revelation. According to Revelation, the appearance of color in our ordinary visual experience provides us with unqualified access to the nature of color. While every proposal about the nature of color must take a stand on how the.. (shrink)

In the seventeenth century, Newton published his famous experimentum crucis, in which he claimed that light is heterogeneous and is composed of rays with different refrangibilities. Experiments, especially the crucial experiment, were important for justifying Newton’s theory of light, and eventually his theory of color. A century later, Goethe conducted a series of experiments on the nature of color, especially in contradistinction to Newton, and he defended his research with a methodological principle formulated in “Der Versuch als (...) Vermittler.” Goethe’s principle included two elements: a series of experiments and resultant higher empirical evidence, which functioned as mediator between the objective and the subjective . Although the notion of experimentum crucis became popular among scientists for reconstructing experimental research and for justifying theories, especially for rhetorical purposes, Newton’s justification of his theory of light and color is best reconstructed in terms of Goethe’s methodological principle. Finally, Goethe’s principle has important consequences for the contemporary philosophical underdetermination thesis. (shrink)

Byrne & Hilbert conceive of color perception as the representation of a physical property “out there.” In our view, their approach does not only have various internal problems, but is also apt to becloud both the intricate and still poorly understood role that “ color ” plays within perceptual architecture, and the complex coupling to the “external world” of the perceptual system as an entirety. We propose an alternative perspective, which avoids B&H's misleading dichotomy between a purely subjective (...) and a realist conception of “ color.”. (shrink)

‘Biochromatology’ can be defined as the study of the relationships between colours, and between colours and design in nature. Certain laws concerning biochromatics can be formulated in the terminology of the Colour Circle. One of them is that planes in warm colours and planes in cold colours never adjoin. Another law is that design is never polychromatic. It seems that the observed biochromatical facts can be explained with the help of the principle “optimal manifestation of colour”, which in turn (...) is based on the formative principles of matter itself.

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.

A Naive Realist Theory of Colour defends the view that colours are mind-independent properties of things in the environment, that are distinct from properties identified by the physical sciences. This view stands in contrast to the long-standing and wide-spread view amongst philosophers and scientists that colours don't really exist - or at any rate, that if they do exist, then they are radically different from the way that they appear. It is argued that a naive realist theory of colour best (...) explains how colours appear to perceiving subjects, and that this view is not undermined either by reflecting on variations in colour perception between perceivers and across perceptual conditions, or by our modern scientific understanding of the world. A Naive Realist Theory of Colour also illustrates how our understanding of what colours are has far-reaching implications for wider questions about the nature of perceptual experience, the relationship between mind and world, the problem of consciousness, the apparent tension between common sense and scientific representations of the world, and even the very nature and possibility of philosophical inquiry.

The dispute between realists about color and anti-realists is actually a dispute about the nature of color properties. The disputants do not disagree over what material objects are like. Rather, they disagree over whether any of the uncontroversial facts about material objects--their powers to cause visual experiences, their dispositions to reflect incident light, their atomic makeup, and so on--amount to their having colors. The disagreement is thus about which properties colors are and, in particular, whether colors are (...) any of the properties in a particular set that is acknowledged on both sides to exhaust the properties of material objects. In a previous paper we discussed at length one attempt to identify colors with particular properties of material objects--namely, with their dispositions to cause visual experiences. Here we shall discuss a different and perhaps more influential version of realism, which says that the colors of material objects are microphysical properties of their surfaces. We shall call this theory physicalism about color (physicalism, for short). In order to evaluate this theory, however, we shall first have to clarify some methodological issues. Our hope is that we can bring some further clarity to the question of color realism, whether or not we succeed in our critique of the physicalists' answer. (shrink)

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.

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)

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)

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.

The early modern distinction between primary and secondary qualities continues to have a significant impact on the debate about the nature of color. An aspect of this distinction that is still influential is the idea that the mind-independence of color requires that it is a primary quality. Thus, using shape as a paradigm example of a primary quality, a longstanding strategy for determining whether color is mind-independent is to consider whether it is sufficiently similar to shape (...) to be a primary quality. However, I’ll argue that the idea that the mind-independence of color requires that it is a primary quality is mistaken, and that, to the contrary, while color is not a primary quality, it is mind-independent. I’ll propose an alternative understanding of what the mind-independence of color requires. This alternative models color perception on an information filter. According to this model, mental qualities that I’ll call media qualities are involved in color perception. The involvement of mental qualities suggests mind-independence. However, I’ll argue, their involvement is modeled after the qualities of a kind of filter that provides access to, but does not constitute, filtered qualities. (shrink)

Despite a wealth of data we still have no clear idea what color experiences represent. In fact, color experiences vary with so many factors that it has been claimed that they do not represent anything at all. The primary challenge for any representational account of color experience is to accommodate the various psychophysical results that demonstrate that color appearance depends not only on the spectral nature of the target but also on the spectral, spatial and (...) figural nature of the surround. A number of theorists have proposed that this dependence is an aspect of the visual system's constancy mechanism. However this does not in and of itself tell us what, if anything, is represented in color experience. Ultimately the answer to this question will be informed by one's theory of representational content. I will argue that adopting a molecular scheme of representation enables the development of an account of the represented object of color experience that can do justice to the psychophysical data.

I argue that Democritus presents a theory of colour in which the predominance of atomic shapes and microstructural arrangements are neces- sary but not sufficient for colour vision. Focusing primarily on Democritus’ basic colours, I analyse his microstructural account, providing a new analysis of the natural and technological underpinnings of his method of explanation. I argue that the notion of predominance allows Democritus to account for both the varia- tion and the repeatable correspondence of colour perception by setting limits on (...) possible microstructures. This account, however, is complicated by the evidence for a Democritean theory of colour transformation and distorted vision, which arise from a dynamic interplay of features at the level of microstructures and at the level of perception.

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 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.

This paper aims to present and evaluate the (unduly neglected) account of the essence of colours developed by the early phenomenologist Adolf Reinach. Reinach claims that colours, as regards their nature or essence, are physical entities. He is opposed to the idea that colours are “subjective” or “psychic”. It might be the case that the colours we see in the world do not exist but are mere appearances. However, their non-existence would not entail any change in their essence: that (...) is, they would not be psychic, but would just be non-existent physical entities. In Reinach’s view, we can be “ontic-neutral essentialists” about colours: we can remain neutral as to the existence of colours but still make claims about their essence. In the first part of the paper, I present Reinach’s take on the essence of colours. In the second part, I address his existential neutrality about colours; in particular, I argue that Reinach’s ontic-neutral essentialism brings to the fore a seldom noted but crucial distinction to be made in the discussion of colours, that between empirical and metaphysical non-realism about colours.

In previous work, I have defended a non-standard version of intentionalism about perceptual experience. According to the doxastic account, visual experience is a peculiar kind of belief: belief with “phenomenal” or looks-content. In this paper, I investigate what happens if this account of experience is combined with another idea I find very plausible: That the colors are to be understood in terms of color experience. I argue that the resulting phenomenal account of color experience captures everything essential to (...) what has been called the “natural concept of color”. And I show that circularity worries are not aggravated by adopting this account instead of more standard forms of intentionalism—rather, they can be dispelled along the same lines. (shrink)

The chapter argues from an ethology-inspired internalist perspective that ‘colour’ is not a homogeneous and autonomous attribute, but rather plays different roles in different conceptual forms underlying perception. It discusses empirical and theoretical evidence that indicates that core assumptions underlying orthodox conceptions are grossly inadequate. The assumptions pertain to the idea that colour is a kind of autonomous and unitary attribute. It is regarded as unitary or homogeneous by assuming that its core properties do not depend on the type of (...) ‘perceptual object’ to which it pertains and that‘colour per se’ constitutes a natural attribute in the functional architecture of the perceptual system. It is regarded as autonomous by assuming that it can be studied in isolation of other perceptual attributes. More generally, the chapter argues on the bases of corresponding empirical and theoretical evidence that perception cannot be understood as the ‘recovery’ of physical world structure from sensory structure by input-based computational processes. Rather, the sensory input serves as a kind of sign for biologically relevant aspects of the external world that activates biologically given conceptual forms with their internal parameters. Although the sensory input is a causally necessary requirement for the activation of conceptual forms, the perceptual computations triggered are under the control of an internal programme based on a set of conceptual forms.

: According to a consensus of psycho-physiological and philosophical theories, color sensations (or qualia) are generated in a cerebral "space" fed from photon-photoreceptor interaction (producing "metamers") in the retina of the eye. The resulting "space" has three dimensions: hue (or chroma), saturation (or "purity"), and brightness (lightness, value or intensity) and (in some versions) is further structured by primitive or landmark "colors"—usually four, or six (when white and black are added to red, yellow, green and blue). It has also (...) been proposed that there are eleven semantic universals—labeling the previous six plus the "intermediaries" of orange, pink, brown, purple, and gray. There are many versions of this consensus, but they all aim to provide ontological, epistemological and semantic blueprints for the brute fact of the reality of color ordained by Nature (evolution). In contrast to this consensus, we have argued that "seeing color" is not a matter of light waves impacting on our eyes, producing sensations to be categorized and labeled in the "color space" in the brain. While electrochemical events may unproblematically be regarded as the causal precondition for seeing color, the reception of sensations in "the color space" as semantically labeled natural categories, kinds, or information, is a "just so" story: it is Wittgenstein's beetle in a box. In contrast we consider that the authority of this consensus might better be regarded not as the result of the truth-tracking of nature, but as the sociohistorical outcome of philosophical presuppositions, scientific theories, experimental practices, technological apparatus, and their feed forward into the lifeworld. The question we shall therefore explore is whether, or to what extent, we ourselves are changed, as the conditions of production of color science change. Thus we are doing a kind of anthropology at two levels: of color science itself (and its effect on our own lifeworld), and of those studied by the "anthropology of color". As befits this stance we are agnostic about the theoretical entities of color science (cf. van Fraassen 2001), and within this new context, we propose to cross-cut object-and-subject, organism-and-environment (the bedrock of color science) in socio-historical ways. Our approach is in part inspired by, but not the same as, that of Gibson, in that we wish to pursue the notion of "social affordances" (Burmudez 1995). We suggest that color has become a naturalization through science-based technologies, which, through praxes and materializations, have become the perceptual and cultural entities that structure experience and understanding in the lifeworld. It is this naturalization that we shall refer to and characterize as "the historically inflected exosomatic organ". Consequently we shall explore the historical ontology of "color" without assuming an underlying biological constant (Dupré 2001). In part 1 we show the flimsiness of the evidence for the three dimensions of color, borrowed from physics, and fine-tuned to a "standard observer" (a "spectral creature" with a phenomenal "color space"). In part 2 we address the structuring of hue through the development of color circles and color spaces. This is followed by a review of the evidence for unique hues. Again the evidence is shown to be flimsy. We then show that an isolated domain of color is a particular kind of model, not a "natural given". In part 3, after reviewing what is referred to as "the isomorphy thesis," we discuss the exemplary case study of Berlin and Kay (1969). This illustrates the pull of stadial models presupposed by their evolutionary theory of color language. The Berlin and Kay paradigm proposes that American English color terms are incorrigible and can provide the universal metalanguage. We conclude by presenting an alternative account, namely that we ourselves are changed as the conditions of production of color science change. We argue that it is better to regard "seeing-color" as a historically inflected exosomatic organ that provides social affordances for those trained to grasp them. (shrink)

The precise nature of microaggression purposely obscures the exploration of the intentionality of perpetrator and the quantification of the harm committed. The act fits neatly into a system that privileges some and validates their reality to themselves and to us. This paper explores microaggression and recommends strategies for avoiding its harms.

One of the most salient facts about our experience of the world is that objects appear to have colors. This feature of our experience is both striking and pervasive. Indeed, representations of colors of objects are among the most notable deliverances of the visual modality, which is perhaps our most important source of information about the world. For this reason, among others, questions about the nature of color have crucial significance for a variety of philosophical subjects including perception, (...) ontology, epistemology, semantics, and philosophy of mind. But the nature of color is a fascinating philosophical topic in its own right, and there has been a significant increase in the philosophical attention paid to this matter in recent years. In this essay I'll survey some of the main views about the nature of color in the contemporary literature and attempt to lay out some of the arguments that have been used to support or reject various of these accounts.

There is a growing consensus in the philosophical literature that sounds differ rather profoundly from colors. Colors are qualities, while sounds are particulars of some sort or other, such as events or pressure waves. A key motivation for this is that sounds seem to be transient, to evolve over time, to begin and end, while colors seem like stable qualities of objects' surfaces. I argue that sounds are indeed, like colors, stable qualities of objects. Sounds are not transient, and they (...) do not seem to be, even though they are typically perceived transiently. In particular, sounds are dispositions of objects to vibrate in response to being stimulated. This stable property view of sounds aligns nicely with, and owes an inspirational debt to, reflectance physicalist accounts of color. The upshot is a unified picture of colors, sounds, and the perception thereof. (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)

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)
