A Retrospective Of Katy Perry's Rainbow Hair Through The Years

Who knows what Katy Perry's hair color is now, or what it will be this time tomorrow? 

It seems any color is game, as she told Glamour earlier this month, "Who knows what kind of woman I’ll be that night?" There are blogs about her hair, endless articles, and heck, we've even given the subject its own page.

To celebrate Katheryn Elizabeth "Katy" Hudson's 31st birthday, which falls on Oct. 25, we take a trip magical enough for Rainbow Brite through the singer's technicolor hairstyle history.

It's proof that, even if you're born with "boring dishwater squirrel brown" hair, when you're Katy Perry, any hair color is a good hair color.
