The colour centre is a region in the brain primarily responsible for visual perception and cortical processing of colour signals ... is located in the calcarine ...
Color processing in the extended V4 occurs in millimeter-sized color modules called globs. [30] [31] This is the part of the brain in which color is first processed into the full range of hues found in color space. [37] [30] [31] Anatomical studies have shown that neurons in extended V4 provide input to the inferior temporal lobe. "IT" cortex ...
Three types of retinal cone create signals that get transformed in the visual pathway to create the perception of color. [1] [5] However the neurons processing them in the retina, lateral geniculate nucleus, and V1 and V2 early parts of the visual cortex encode using the opponent process only a limited range of colors that does not reflect the dimensions of perceptual color space.

The color of chemicals is a physical property of chemicals that in most cases comes from the excitation of electrons due to an absorption of energy performed by the chemical. The study of chemical structure by means of energy absorption and release is generally referred to as spectroscopy .

Neuromelanin (NM) is a dark pigment found in the brain which is structurally related to melanin. It is a polymer of 5,6-dihydroxyindole monomers. [ 1 ] Neuromelanin is found in large quantities in catecholaminergic cells of the substantia nigra pars compacta and locus coeruleus , giving a dark color to the structures.
Interblobs are areas between blobs that receive the same input, but are sensitive to orientation instead of color. They output to the pale and thick stripes of area V2. Blobs are on the koniocellular pathway. This pathway begins at the photoreceptors which then relay signals to the 'K' ganglion cells in the retina. The pathway then continues ...
Grapheme–color synesthetes tend to have an increased thickness, volume and surface area of the fusiform gyrus. [2] Furthermore, the area of the brain where word, letter and color processing are located, V4a, is where the most significant difference in make-up was found. Though not certain, these differences are thought to be part of the ...
