    Black + white = brown. Mostly.

    There are 4-6 genes involved in any given person in determining skin colour, and there is some incomplete-dominance. Also, even in simple Mendelian genetics you can have co-dominance.

    I read somewhere that there are about 20 alleles determining skin colour in humans. And there is no simple dominance/recessive relationship. Thus, the expression of skin colour is a continuum. Everything from albino white to ebony black, and every possible tone in between.

    As well texture, gloss, and surface blood vary. Some people look relatively green, or blue.
