Representation of Color^☆

Abstract

Color is an important part of our visual experience. The swirls of blues, yellows, and greens in Van Gogh's Starry Night affect a viewer in a way that a black-and-white rendition cannot. Color vision allows us to find a green bell pepper among red ones and predict how good it will taste. This article describes briefly the aspects of light that are most important for color vision, the processing of color information in the retina and thalamus, and color processing in the cerebral cortex. Also, some of the recent computational modeling approaches of color processing are discussed at the end.
