retinex theory

a theory based on the idea that color registration is carried out in the brain. Demonstrations such as the Land effect suggest that wavelengths register on the color-sensitive components of the retina as color-separated “photos.” The visual mechanisms in the brain then compare the average of the long-wave photos with the average of the shorter-wave photos, assigning different colors according to the ratios between them. Also called Land theory of color vision.
