Open Question: Ideas for my character's appearance?

like hair color, hair style, eye color, etc etc details would help too it's for a anime/cartoon idea like what would fit with her personality... description is just short in general, other stuff will be shown later personality: emotionless girl , extreme doormat, secretive, losing a grip in reality [kind of lost in her own world], slipping into apathy, detached from life and other people, but has somewhat of an obsession with weird and creepy things, almost never says anything, doesn't get involved in anything, or makes eye contact other people think she's weird/scary/ or pity her the genre could be mystery/drama/ or sci-fi/horror it's not entirely finished so.. *other tips would help too and if u don't like it just don't answer ***and i want it to look kind of unique too, maybe besides wacky hair color lol OTHER:[already decided] bags under eyes, no piercings, tattoos, makeup, etc. wears baggy/non-revealing clothing. no glasses
