Katy Perry Dyes Hair "Slime Green": See Evolution of "Roar" Singer's Rainbow Locks

Katy Perry is a pop culture chameleon. She emerged into the songstress scene with freshly dyed black hair, hiding her blonde, homely looks. A black bob has been her go to ever since her 2008 hit "I Kissed a Girl" captured audiences attention. Since then, she's tried a handful of other colors as her musical career progressed from the wild to the goofy, from Smurfs to "California Gurls" and beyond. And with Tuesday's reveal of a green-colored 'do, Perry has officially dyed her hair every color of the rainbow. Take a peek back at the singer's wild evolution.
