Just call her Ginger.

Katy Perry's gone from drop dead brunette to coppery redhead. The singer showed off her new color—Hollywood's trendiest hue of the week—while taking a dip in Florida.

But enjoy it while it lasts. The "Last Friday Night" singer recently tweeted that she won't be a redhead for long. "So I didn't get to the exact color I wanted from being black for so long! 2get to goal I have 2b GINGER for 3WKS."

Any guesses where on the color spectrum Katy hopes to land?
