The inferotemporal cortex is involved in both face perception and color perception. It may be in this region that the brain processes visual data on the hue and luminosity of human skin.
If you are a member of the International Society for Human Ethology, you can read my latest article: Hue and luminosity of human skin: a visual cue for gender recognition and other mental tasks.
Face recognition takes place within a distinct heritable module of the brain and includes the ability to distinguish between male and female human faces. To identify gender, this module targets a number of sexually dimorphic features, particularly the hue and luminosity of facial skin. Men look browner and ruddier in hue because melanin and blood are more present in their skin’s outer tissues. Women have a higher luminous contrast between their facial skin and their lips and eyes. Hue seems to provide a “fast channel” for gender recognition. If the observer is too far away or the lighting too dim, the brain switches to the “slow channel” and targets luminosity. In addition to assisting gender recognition, the skin’s hue and luminosity may also alter the observer’s mental state in a number of areas, ranging from sexual attraction to emotional distancing.
