I've highlighted my hair a very light blonde once, which only showed up under florescent lights cause I have dark blonde hair anyways. Last summer I put orange streaks in it, and it looked weird at first, but after a couple of days it looked very nice and very subtle. Next I might try pink or purple. I don't think I'll ever do an all over dye job because my hair is very curly, I don't think frizzy pink curls would be very pretty. xD
