When it comes to celebrities, you never know quite what you're going to get, and at the Grand Opening Weekend of 1OAK Nightclub in Las Vegas (January 27, 2012), Katy Perry didn't disappoint.
It should be noted that to achieve these types of hair colors, someone with naturally dark hair (like Perry) needs to lighten their hair to a level sufficient to allow the vibrant tone of the new color to shine through.
Simply applying a teal color to dark hair will only result in a subtle tinting, visible only where the light glints off the strands.
