The 24-year-old actress just ditched her Tang-colored hair and went back to a more familiar shade of brown.

In case you missed it, Kristen dyed her hair a bright tangerine hue for her role in American Ultra — an upcoming action comedy about a stoner whose "sleepy, small-town existence is disrupted when his past comes back to haunt him in the form of a government operation set to wipe him out," according to the film's synopsis.

Now, though, she's back to being a brunette as she and Nicholas Hoult head to Tokyo and Singapore to film Equals, a sci-fi drama set in a dystopia devoid of emotions.

When Variety asked Kristen and Nick about their working relationship, Kristen joked, "I can’t stand him."

Nick answered sincerely, though: "It's always a weird position to be put in any film where the director chooses two people and is saying 'Hey, potentially in this world I'm creating you two could fall in love.' … But the kind of environment [director Drake Doremus] created was straightforward and easy. Kirsten is a great actress and that just makes it very relaxed and my job very easy."

Her hair looks equally chillaxed now!
