Colour Centre
The color center is a region in the brain primarily responsible for visual perception and cortical processing of color signals received by the eye, which ultimately results in color vision. The color center in humans is thought to be located in the ventral occipital lobe (VO) as part of the visual system, in addition to other areas responsible for recognizing and processing specific visual stimuli, such as faces, words, and objects. Many functional magnetic resonance imaging (fMRI) studies in both humans and macaque monkeys have shown color stimuli activating multiple areas in the brain, including the fusiform gyrus and the lingual gyrus. These areas, as well as others identified to have a role in color vision processing, are collectively labeled visual area 4 (V4). The exact mechanisms, location, and purpose of V4 are still being investigated.

“O Paddy dear, an’ did ye hear the news that’s goin’ round?
The shamrock is by law forbid to grow on Irish ground!
No more Saint Patrick’s Day we’ll keep, his colour can’t be seen,
For there’s a cruel law agin the wearin’ o’ the Green!”

“To make our idea of morality centre on forbidden acts is to defile the imagination and to introduce into our judgments of our fellow-men a secret element of gusto.”
