Colour centre in humans as an area specialized for colour vision. V2, also called the prestriate cortex, is believed to have a small role in colour processing by projecting signals from V1 to the V4-complex. Whether or not colour selective cells are present in V2 is still being investigated. Some optical imaging studies have found small clusters of red-green colour selective cells in V1 and V2, but not any blue-yellow colour selective cells. Other studies have shown that V2 is activated by colour stimuli, but not colour after images.[8] V4 also has feedback on V2, suggesting that there is a defined network
Flowers Are Red original version is excerpted. The song tells the story of a little boy who on the first day of school started drawing pictures of flowers using many different colors. The teacher (sung by Chapin in a falsetto voice) tells him that he should not be coloring because it is not time for art, and in any case, the boy is coloring the flowers all wrong and that he should paint them red and green, "the way they always have been seen."
