Lilly is purple because of her mutation. If you look at her outfit, she was probably a gardener for the Skiing lodge in pre-war times. Now, imagine frostbite. If you got it on your toes or fingers or something it would make it look purple/black. She inhabits a snowy area.
Cold weather + Frostbit + Mutation = Purple Monster.
It's probably a big case of irradiated frostbite.
