[Yes, if you turn off customization restrictions. By the way, sun elves have bronze skin, while forest elves have copper and tanned skin. And I still don't see the point in introducing new faces for non-white elves. You can make a black-skin elf anyway.
So what's your complaint against people requesting that Larian add more faces that allow you to make an elf that appears ethnically black (or non-Caucasian)? If we already have the ability to turn off restrictions to make any colour combination, why not have that restriction enable more face options?
One answer: Lore. Sun elf are supposed to appear in a certain manner. Wild elf on another. Moon elf on another. Drow on another. But they all share with some difference the same bone facial structure as they are elves not humans.
