Katy Perry is a muse for many colorists, given her adventurous nature when it comes to hair color. We know she's never afraid of those bright, head-turning shades — just take her green highlights for example. And as a brunette, it takes time to attain and maintain these bright hues, so we give her props for her chameleon-like, hair-changing abilities. Of course, Katy would bring out every color in the spectrum for her Prismatic World Tour. She even gave us a sneak peek at the wigs she'd be wearing on Instagram!
Take a look at her showstopping hairstyles, and let us know which is your favorite! We're partial to the pretty pastels.
