If you were 20 or older I'd say: none of the above. Knock it off and forget about that. <br />
BUT since you're exactly the right age to want to do that to your hair (so did my daughter and by the time it washed out / grew out she was tired of it) I say BLUE!
What about all three?
I would love to have blue streaks in my hair.
I had purple and got so many compliments every where I went it was unreal!
Blue, light blue.
go with all 3
I'm getting light blue
