What should I name this character in the story I'm writing?

Okay. I am writing a story and I can't seem to figure out a name for my female main character. She's sort of an outcast, kinda...punk-ish...if you will. I was thinking maybe a shade of purple as tha name, cause that would go with the story...but anyway she is - rebellious, affectioniate, closed, guarded, secretive, caring, rejects change, gloomy, negative, inconsiderate, uncooperative, fearful, hesitant/unsure/indecisive, uncommited, does what is conveniant, undetermined/gives up, unenthusiastic, apathetic, indifferent, lacks faith in life, lacks faith in self, lacks faith in others, unfocused, distant, goodwill, ungrateful, unappreciative, lazy, dishonest, easily jealous, envious, pessimistic, reliable, unsystematic, disorganized, disorderly, insists on own view, suspicious, mistrusting, insecure. I was thinking something like Violet, Lavender, Orchid, Lilac, Amythest, Magenta, etc. But it doesnt have to be a color of purple. I was also thinking along the lines of October or Winter...or...Casandra. Do you favor any of these? Any other suggestions? I don't want the name to sound too unrealistic...
