I had green highlights once in high school and it was reddish brown once, but other than these two times, I had my original hair colour then (which is light brown/dark blonde). After... well, I started with reddish blonde, then blonde, chestnut brown, black, ruby red, pink, platinum blonde, magenta and right now I have some mixture of magenta and chocolate brown. That is twelve I think. I never had blue or purple.
