Katy Perry's Transformation Into A Human Rainbow Is Officially Complete

Finally, the moment we've all been waiting for has arrived—Katy Perry has worn every shade of the rainbow (plus pink!) on her head.

Congratulations, y'all, we did it. The rainbow was completed on Wednesday (Sept. 16), when Katy attended the 2015 Harper's Bazaar Icons event with a new red 'do. While it's not quite Rihanna-level cherry red, it's definitely redder than KP has ever ventured before.

To celebrate the momentous occasion, we rounded up Katy's colorful hair—peep the full spectrum below!
