Color Constancy with Derivative Colors
CoRR, 2016 Information about the illuminant color is well contained in both achromatic regions and the specular components of highlight regions. In this paper, we propose a novel way to achieve color constancy by exploiting such clues. The key to our approach lies in the use of suitably extracted derivative colors, which are able to compute the illuminant color ...

Proceedings of the National Academy of Sciences, 1931 In another paper, L,3 the author has given a proof of a formula for M(λ), the number of ways of coloring a graph in λ colors, due to Birkhoff. The numbers m ij , in terms of which M(λ) is expressed, are here studied in detail; a method of calculating them is given.

Color categories and color appearance [PDF]
Cognition, 2012 We examined categorical effects in color appearance in two tasks, which in part differed in the extent to which color naming was explicitly required for the response. In one, we measured the effects of color differences on perceptual grouping for hues that spanned the blue-green boundary, to test whether chromatic differences across the boundary were ...

Color realism and color science [PDF]
Behavioral and Brain Sciences, 2003 AbstractThe target article is an attempt to make some progress on the problem of color realism. Are objects colored? And what is the nature of the color properties? We defend the view that physical objects (for instance, tomatoes, radishes, and rubies) are colored, and that colors are physical properties, specifically, types of reflectance.
