The Keeping Up With The Kardashians star was pictured sporting the eye-catching hairdo as she visited a recording studio on Monday, 26 October.
Kylie teamed her mermaid-esque locks with super skin tight leggings which, unfortunately for her, went a tad see-through in the camera flashes. She completed her sports chic look with a white baseball cap, aviator shades, a long-sleeved crop top and a cute little black Chanel bag.
It's not the first time we've seen Kylie sporting this shade of green hair: she first debuted a minty hue while opening a new Sugar Factory store in New York in September.
Kylie loves switching up her style having tried a multiple of lengths and colours over the years including black, blonde, pink and blue.
Meanwhile, there's no word on why the 18-year-old was at a a recording studio: visiting rapper boyfriend Tyga perhaps? Or working on music of her own?
Kylie featured in Tyga's racy video for his song '$timulated' and has often been rumoured to want a music career of her own, although she played down the idea of pursuing pop stardom during a June 2015 interview, saying simply: "I don't know. I like to keep all that to myself."
Watch Kylie in '$timulated' - warning, it's explicit!
