Two ladies who really rock the brightly colored hair are The Dainty Squid and Love, Elycia. They both have AMAZING purple hair right now. And I may have become even more jealous of their hair now that I've photoshopped it on to myself! But I'll go ahead and leave the amazing technicolor hair coloring to Elycia and Kaylah. They are definitely masters of the art of rainbow hair.
What color have you daydreamed of dying your hair to?
