Stained Half-Elf (5e Race Variant)
From D&D Wiki
Stained half-elves are victims of an unfortunate magical effect that effects a small portion of half-elf births. The magical blood of an elf seems to manifest differently in them. Their hair resembles stained strands of various colors, from silver, red, green, and blue. Stained half-elves also usually have heterochromia eyes, and blush that is not the usual rosy pink. They command a good deal of control over magical powers due to their unique heritage.
