“Game of Thrones” star Maisie Williams has gone pink.

The 21-year-old actress, who plays Arya Stark on HBO’s hit show, naturally has brown hair, but she showed off a new rosy pink hair color on her Instagram story Wednesday.

She first posted a selfie while sitting in front of a salon mirror with a towel wrapped around her hair and another over her shoulder. She followed the photo up with a dark video in a car where you can briefly see the pink in a quick flash of light.

Williams isn't the only "Game of Thrones" star to dye her hair.

Emilia Clarke dyed her brown hair blonde in September 2017 to match the iconic color of Daenerys Targaryen's hair.
