Document Summary
Vision: color vision-theories, trichromatic, opponent process, constancies, depth perception, monocular cues, binocular cues, gestalt principles. Trichromatic theory (electromagnetic spectrum: (perceptual evidence, additive theory: e. g. , color tv/monitor (image to left, subtractive theory: e. g. , mixing paint color blindness. Perceptual evidence: adding colors together (red, green, blue) project yellow, absorbing white light form the environment (subtractive theory), blue is absorbing everything except blue, red is absorbing everything except red. 3 colors involved that can be rearranged in different combinations to detect viability. Can see yellow because combination of red and green. Pink dots (circle) were gone not b/c it was programmed into it but because of the after image of the pink messing with our color vision. A lilac image gives off a green after effect (hinton"s lilac chaser ) Green and lilac are somehow linked together. Blue=yellow, green=/red/pink: 2 opposing process of colors can both, psychological evidence exist, ganglion cells: receives input from many photoreceptors. Are good for color perception as well.
