In the interest of slightly more racially-sensitive worldbuilding, so your one marquee dark-skinned race isn't all evil, I'd make a point of having diverse elves.
I had a setting back in college with elves that had large nations in northern mountains, so they looked loosely Scandinavian, only more sharply featured. Then there were elves who lived in a forest that had once burnt down, who all tended to have red hair and tanned skin; elves who had lived in the darkest wooded valleys and had drow skin tones but purple, gold, or crimson hair; elves who had a nation in an archipelago with brown skin and curly black hair; nomadic seafaring elves who looked roughly Polynesian; and the actual 'dark elves' with slate black skin and white hair, who lived in a dreamscape demiplane that lay under the surface of the world.
Each of the groups had names for the ethnic group, plus names for the various nations they lived in, since they weren't monolithic.
Just be a tad more creative than the designers were in the 70s and 80s, and strive for more representation.
