Youre right there! but all elves cant look exactly the same!
Yes, in fact there should be a lot of difference in the colour palettes of our Elf subraces. Sun Elves are warm toned, so golds, reds and coppers. Moon Elves are cool toned, so whites, blacks and blues. Wood Elves are browns, greens and bronzes. And Drow are greys, blacks, and silvers. Although that last one has varied a lot by edition, let us not forget the eggplant purple Drow of old.
