Quick lesson on genetics! The reason that humans in the real world have lighter skin (mainly aryans, but also Asians) is because they mixed in with the preexisting relative species (Neanderhals) Humans naturally look negroid.

Now, in the case of the water tribes, they seem to be in the same boat as the native Americans they are modeled after. The human "homeland" in avatar likely was somewhere in the earth kingdom (guess), but the neanderthals of the avatar world (probably mainly in a continent that no longer exists, mixed in with people of air nation and fire nation descent. Many people in the Greater Earth Kingdom remain relatively dark, as do water tribe members, because thy likely didnt mix in, or escaped the breeding all together, like their counterparts in northern Earth Kingdom or The Fire and Air Nations.
