Document Summary
Brightness: 3 elements determine the overall richness of color, colors that are weakly saturated look closer to white. Evidence for trichomacity: 2 ways to think about color, trichromacy, 2 sources of evidence are psychophysical and physiological (3 cones that correspond to 3 different types of cell, opponency, 4 sources of evidence, psychophysical- using hue cancellation. To make red go away vamp up the opponent color to make the red go away. Color afterimages, color categorization (people tend to think in 4 categories: response profile of rgc- most salient evidence. Some cones will inhibit rgc and some will inhibit rgcs firing rate. Color constancy: ability to compensate for the light source to perceive a color as the same, something that is blue because it reflects light at that wavelength. In order to perceive color across a variety of lighting conditions you have to compensate for the light source. How motion is computed from the retinal image.
