Kylie Jenner is truly a chameleon when it comes to her hair.

Just when we were getting used to her blonde locks, the 18-year-old reality star changed it up again big time, rocking bright green locks at the Sugar Factory grand opening at American Brasserie in New York City on Wednesday night.

But what's even more impressive is Kylie was still sporting her bottle blonde hair when she walked her brother-in-law Kanye West's fashion show at New York Fashion Week, just mere hours before.

Wednesday actually marks the second time Kylie has walked one of Kanye's fashion shows. In February, she was featured in the 38-year-old rapper's Adidas show, this time hiding her hair under a skin-tight cap.

So is it safe to say we all know who Kanye's favorite Jenner sister is? Because plenty of people were surprised to see 19-year-old Kendall Jenner not even make the front row at his fashion show, with Kim Kardashian and her sisters Kourtney and Khloe all seated in front of her.

But don't feel too bad for the supermodel -- she walked for Michael Kors, Diane Von Furstenberg, and Givenchy during NYFW.

ET actually caught up with Kylie on Tuesday at the Vera Wang Spring 2016 fashion show, where she talked about her buzzed-about new mobile app -- specifically, how some fans are not happy about the $2.99 monthly subscription fee.

"I put so much time into it," Kylie stressed, talking exclusively to ET. "And it's stuff that I would never choose to share in a million years, but deep down I want my true fans to know, like all my personal stuff and tricks -- stuff that I would never share on Instagram. So if they want to know real personal stuff that, like, makes me a little uncomfortable to share, then I don't think it's that big of a deal."
