Katy Perry's Hair Goes Over the Rainbow

Katy Perry is pretty unpredictable when it comes to her red carpet style, but the one consistent thing has been her raven hair -- save for a blue wig or two. But not anymore. The singer has been on a mission to get to a "secret" hair color, and her journey has taken her through five hues in just over a month! Take a look at her hair transformation here:

Black Beauty: Birth to June 16, 2011
Katy Perry's natual hair color is a beautiful jet black. Her raven locks were the standard up until about six weeks ago, then she began dabbling in dye. With the help of bleach and a lot of patience she's ditched her dark mane.

Hot Ginge: June 17

Katy alerted her fans about her first coloring job on June 17. "Tonight I dye my hair a different color... Can you guess which color?!" she wrote.

Hours later she gave an update. "So I didn't get to the exact color I wanted from being black for so long! 2get to goal I have 2b GINGER for 3WKS #paybackfromGINGERGodsFML!" she said about the dye gone awry.

And she didn't end the updates there. "If I don't wait 3wks, I'll end up w/no hair or a #pixie90scutw/abarretteinthefront It's okay, I'll get to my secret color(s) soon!," she added.

The starlet flew below the radar, and especially out of camera shot, for a couple of weeks before surfacing as a "ginge." On July 1 she posted about her new locks: "On my way to launch PURR in TORONTO! FINALLY CA has PURR avail to them! P.s. If u see a ginger haired girl that looks like me, it's me!" she wrote. Sure enough, she was spotted the next day with brassy locks.

Blue Belle: July 4
Katy gave her processed locks the night off and donned a wig for her July 4 gig in Montreal. She threw on a natural-looking black wig and then spiced things up with a bright blue one.

This wasn't the first time Katy's rocked an Smurf Blue wig. She did so at the Kids' Choice Awards, where she got slimed onstage. And it's been done before. Many stars have also sported the same hue: Gwen Stefani, Perez Hilton, and, of course, Marge Simpson.

Blondie: July 24

Katy made it no secret that her goal was to drastically lighten her locks, and sure enough she showed up to the premiere of The Smurfs a blond!

She paired her golden hair with a short sparkly dress, and both her new 'do and silly dress got very mixed reviews. Perhaps the luke warm reaction was what prompted her to go home that night and dig out the dye again. She wrote after walking the red carpet: "I have been dying my hair since 10pm! Good GOD let me get to my destination tonight! #beenblack #beenblue #beenhotginge #beenblonde #now..."

Pretty in Pink: August 1
Ms. Perry's hair has certainly taken a beating with all that bleach, and luckily her current hue didn't require any further stripping. Instead she added another color: pink! The songstress debuted her cotton candy color Monday while out and about in LA. Will this be the end of the rainbow? Stay tuned.
