Sort Skin Tone By Ethnicity

As everyone else has said, this is a bad idea. Besides the fact that dividing sims by race would just upset people, it's also unrealistic. For example, I'm a black girl. We come in basically all shades; from dark brown, to pale as snow. You've also got Indians and middle eastern people, who also come in pretty much all shades. East asians can be anywhere from pale to a tannish brown color. Even white people come in various shades, especially if they're from a place like Greece or Italy. Some white people can get mistaken for people of color because of their tan. And how about mixed people, huh? Lets say a sim's mom black, and the dad is Asian? What skin color is that? So yeah, bad idea.
