Just for curiosity, here are some statistics about the Elves.

Well, I can still understand the gray skin in relation to underground dwellers.

I don't quite get it; white would be more logical, in my opinion. And skin, as a rule, is the result of a curse. At least they aren't afraid of the sun.

Okay, let's forget about their fascism, although the creators clearly went overboard with that, but the fact that they all have jaundice and eunuchoidism, I can't ignore.

They have a certain standard. Those who don't fit in are drowned and hanged. Apparently, yellowness is valued among them.

Forest elves with brown skin (or maybe it's fur) – that's something else.

I don't remember very well, but aren't they relatives of the Khajiit?
