Katy Perry is a walking, breathing rainbow -- of hair colors!  As one of Channel 957's most requested artists for her music she is fast becoming the go-to girl for the latest hair trends.

It's not so much that Katy makes appearances with a new style as it is the color that changes-up.  Earlier this summer, the Firework said she was going back to her blonde roots.  Instead of taking the natural route, Kat has gone from jet black, red, blondish at The Smurfs premiere a couple of weeks ago to pink!

It's kind of fun to watch the progression-o-colors and I'm anxious to see what she decides to do next because I would think that she would be fully blonde by now.  If you've missed any of the stages I've mentioned just click here and follow the links!
