Color contrast is 'seen' by the brain early doors
Date:9/7/2007

ary visual cortex surgically removed in 1973 for treatment of abnormal blood vessels in the brain.

Professor Charles Heywood, who leads Durhams Psychology Department, added: People can distinguish between colours partly because of the contrast with its background. If someone has lost that ability through brain damage, it means that they might see colours as changing all the time. The colour of clothes, and indeed everything else we see, would change dramatically, depending on the colour of light which shines on them.
