Ever since she appeared on the music scene with "I Kissed a Girl" in 2008, Katy Perry had us hooked with both her catchy tunes and her tendencies to rainbow-bright beauty. She doesn't just rock technicolor hues in music videos and for her stage performances — she makes these shades look totally natural every day via nail art, makeup, and (of course) her ever-changing hair. Katy's coif has been privy to practically every Pantone swatch possible now (she even looks good in green!) Celebrate her 30th birthday with a look back at her most memorable hair looks.
