Unrelated to inductive reasoning, but a fascinating fact is that humans are naturally dark skinned (native Europeans used to have blue eyes and dark skin), some humans today have melanin mutations that cause them to be lighter, and chimpanzees are all white: they are just covered in black hair.
Related to skin pigmentations, a "white" horse with a black nose is, in fact, a fully greyed-out horse. True white horses have pink noses and are much rarer.
