COLOR CONSTANCY

COLOR CONSTANCY. VISN2211 David Lewis Sieu Khuu. COLOR CONSTANCY THEORY. Absolute rates of photopigment absorptions do not explain color appearance. Color appearance depends on local contrast of cone absorptions. Color perception of an object is relative to the colors in the surround.
