Katy Perry Dyes Her Hair 'Slime Green For Spring'

Forget pastel- this spring, green hair is all the rage, according to Katy Perry.

The "Dark Horse" singer posted an Instagram pic on Monday showing off her new hair, which was dyed a vibrant shade of green, save for her bangs and roots which were kept a dark shade of black.

"SLIME GREEN FOR SPRING by my bb's @neeenaboo & @brantmayfield at the @mcmillansalon," Katy captioned the photo.

This isn't the first time Katy has pulled a Rihanna: the 29-year-old has also gone purple, blue, blond and a host of other rainbow colours.

Green has been on Katy's radar for a while- John Mayer's ex told E! Online in March that she had been thinking about changing her colour for a while.

"I've wanted to go slime green for a long time," she said. "It's spring time and I think it's time to freshen up my look."

Here's what we want to know: does the hue go well with all her kooky outfits?

Katy's hair was really different back in the day:
