Melanocytes.
Everyone has about the same number of melanocytes, but activity and distribution varies between races. Those with dark skin, such as Negroes, Indians, Sri Lankans, Australian Aborigines etc, have more active melanocytes.

The cells are the epithelial, or skin cells,more specifically, melanocytes, which contain a pigment, called melanin. Melanin helps absorb UV sunlight, which explains the evolutionary advantage of having higher concentrations of melanin in areas of the world with alot of sunlight and UV radiation. This is why in areas near the equator, which receives the highest average sunlight annually, the average skin tone of the inhabitants is much darker than in other parts of the world.

Melanocytes, located in the epidermis, produce melanin, which is the pigment that gives the skin color.

the cell is melanin. The thicker the skin, the more layers of cell with melanin in them.

I think it really is too bad that America is so STUPIDLY politically correct, that you had to say "this is not racist" in your question. Screw those people that are so sensitive. They MAKE me feel racist...
