Rainbow hair
I have actually been considering getting rainbow hair... Here are some colorful styles I found.. none of them are quite what I would do, but are narrowing it down for me. :)
My favorite is of the painter on the ground (bottom row of pics, second from the left)
(Yes, I stole these from Instagram and Tumblr :P)
The third pic from the left is close to what I was considering trying with the temporary hair color from thr Dollar Tree, but I changed my mind. Who wants to get colorant all over their clothes? No one.
