Document Summary

Steps of color perception: detection: wavelengths must be detected. 3 types of cones each with different photo-pigments, thus each having different sensitivity to light. All 3 together gives us the overall ability to detect wavelengths from 400nm-700nm: s-cones: short wavelength cones, less sensitive, more rare than the others ( blue , m-cones: medium wavelength cones ( green , l-cones: long wavelength cones ( red ) 1 rod photoreceptor: detects in dimmer light and has a somewhat different sensitivity profile peaking at. One photoreceptor type cannot make color discriminations based on wavelength: explains the lack of color in dimly lit scenes. Opponent of (l-m), {(l+m)-s} & (l+m) color-opponent cells: appearance: we want to assign perceived colors to lights and surfaces in the world. Moreover, we want those perceived colors to go with the object and not to change dramatically as the viewing conditions change. 3 numbers defining color: hue: the chromatic (colorful) aspect of color (red, blue, green, yellow)
