Katy Perry seems to be trying out all the colours of the rainbow in her locks. Seen recently in a rainbow-streaked mop, this trend is a lot tamer than her blue-smurf-hair from the MTV movie awards.
Her vivid hairstyle may be toned down, but it still features enough colour. Against her black hair, Katy Perry's streaks of purple, blue and pink provide an interesting, punk-like contrast. The look definitely matches her catchy and poppy candy land-style tunes.
