Rainbow bright!

Two stars switched up their hair on Tuesday, May 13, opting for rainbow-colored shades instead of the more neutral browns and blondes.

After rocking bright blue highlights for about a week, Kylie Jenner went all in on Tuesday. After visiting the Andy Lecompte Salon in Los Angeles earlier in the day, the Keeping Up With the Kardashians star showed off her new ombre blue hair via Instagram. "My hairs blue. night," Jenner, 16, wrote.

Also stopping by Andy Lecompte for a color change on Tuesday: Rumer Willis. The 90210 alum, who had been sporting orange hair with pink highlights on May 10, transitioned to an allover bright pink shade—reminiscent of a certain cartoon rock star.

"Jem ain't got nothing on me #pinkhairdontcare," Willis, 25, wrote via Instagram, calling out Danny Moon, Pravana guest artist at the Andy Lecompte Salon, who is responsible for Nicole Richie's lavender hair. "Thank you to @majormoonn for kicking ass today."
