Drow

Elves are able to adapt to almost any environment, and the drow are no exception; generations born and raised underground has led to a type of elf that is smaller than average to adapt to the tight spaces. On top of that they are distinguished from other elven subraces by having purple-grey skin and white hair, and eyes that can have a red or purple hue. They are also sensitive to sunlight, often having a difficult time seeing any target that isn't shadowed in some way - another byproduct of being largely subterranian.
