Halloween // Help! Costumes for someone with olive green hair

On Halloween, I'll have olive green and partially light blonde braids in and I can't think of any costume ideas beyond like... a fairy or Mother Earth or the like and I don't necessarily wanna go that route since I kinda dress like that normally. I can't think of anything or any characters that would look fine with green and partially blonde hair. I'm partial to anything more gothic, but I don't particularly care.
