Reply #321: "white pigment"?What the hell are you talking about, there's no such thing

[SemiCharmedQuark]

Black skin is black because of an increased output of melanin. There is no white pigment, just less melanin.

Secondly, if you want to get biological about things, in places where there is fog or large amounts of clouds, less melanin is favored. Why? Because melanin protects from the sun. No large amounts of sun, hey! No need for large amounts of melanin! Not only that, Vitamin K deficiency comes into play.

So really, they should be light skinned savages. But nah, nobody would believe that craziness.

The only thing that could possibly, remotely, be considered "white pigment" would be pheomelanin, and that is a huge huge stretch.
