Document Summary

Take a moment to compare the experiences of watching an old film in black and white, and watching a newly released film in full colour on the giant screen of a movie theatre. Very different experiences in terms of your visual perception! There are three different dimensions of how we experience colour: hue, saturation, and. Hue: actual colour we see (red, green, etc. ) Brightness: intensity of light energy we perceive. Trichromatic theory - three types of cones in retina. Each type makes its maximum chemical response to blue, green, or red. Opponent-process theory consistent with happenings of ganglion cells. Stare at one colour; brain will give sensation of opposite colour on white surface. Researchers believe colour processing starts at level of retina. Is completed in colour detectors in visual cortex. 8% males, 1% females, have difficulty distinguishing colours. Genes for colour vision are carried on x chromosome.
