It has been suggested that difficult-to-quantify differences in visual processing may prevent researchers from equating the color experience of different observers. However, spectral locations of unique hues are remarkably invariant with respect to everything other than gross differences in preretinal and photoreceptor absorptions. This suggests a stereotyping of neural color processing and leads us to posit that minor differences in observer neurophysiology may be irrelevant to color experience.
