It’s not easy being green.

Katy Perry debuted a bright new ‘do on Instagram Monday evening, proving she’s not afraid to switch up her look.

“SLIME GREEN FOR SPRING,” the “Roar” singer, 29, wrote alongside the pic.

While Perry’s most recent hair color has been jet black, she’s no stranger to vibrant dye jobs, having sported pink, blue and purple tresses in the past.

The singer first brought up the possibility of her new look at MOCA’s 35th Anniversary Gala in Los Angeles last month.

“I’m really excited about slime green, but I hope my hair doesn’t fall out,” she told E! News at the time.
