Duh, seriously... RPGs are what you make them, and while about 80% of my players (I'm in Germany) are white, only about 50% of the characters are. The Company of Chaos, for example, has 2 characters actually changing skin color from brown in summer to pale white in winter, a black gnome, and a black/colored human.
My Company of Cyndu group's over 169 characters have plenty of black/yellow/red/brown characters.
If anything, I'm more looking at stereotype settings where the different colors always seem to get similar roles than in our world. Golarion kinda made the same error.
In one of my homebrew worlds, the whites are the barbarian tribes, the blacks the Japanese type martial artists, the yellowish the gypsy type travelers and the red/brown ones the scholars and priests. It was a bit confusing at first but the world is about ready to be playtested.
I'm totally blind to race, kinda, so the Pathfinder paladin and other non-white icons are just nothing out of the ordinary. And I'm happy that in ways of playing in most settings, race matters not at all.
