Singer Katy Perry seems to have taken the title of her album "Prism" too seriously as she has dyed her hair green.

The star has earlier experimented with red, blue, purple, blonde and black hair, and this time she has tried slime green. Her full spectrum is now almost complete, reports eonline.com

The singer showed off the new hue on Instagram, saying: `SLIME GREEN FOR SPRING by my bb's @neeenaboo & @brantmayfield at the @mcmillansalon ????????`

"I've wanted to go slime green for a long time. It's spring time and I think it's time to freshen up my look," said Perry at the 35th Anniversary Gala presented by Louis Vuitton, Museum of Contemporary Art, Los Angeles.

"I'm really excited about slime green, but I hope my hair doesn't fall out. As for a new style, I kind of cut my bangs in haste and now I want them gone," she added.
