Not So Rainbow Bright

Shoes:  Lita, Leggings: Forever21, Pullover: Little Tokyo, Dress: Birthday, Bangle: Joyrich, Headband: Made by me

So I did a subtle version of the rainbow hair I have been gushing over for so long! I love it and im really happy with it, BUT I need your opinions… should I keep it light and pretty, or add a lot more rainbow colors? Its borderline an amazing/bad idea.

What should I do help!
