When it comes to celebrities, you never know quite what you're going to get, and at the Grand Opening Weekend of 10AK Nightclub in Las Vegas (January 27th 2012) Katy Perry doesn't disappoint.
It should be noted that in order to get these types of hair colors, someone who has naturally dark hair (like Perry) needs to lighten the hair's natural color 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 of the hair, visible only where the light glints off the strands.
