Emma Stone made headlines last week when she dyed her hair from blonde back to her signature red after filming "The Amazing Spider-Man 2," in which Stone plays Peter Parker's (Andrew Garfield) blonde girlfriend Gwen Stacy.
Stone, 24, is a natural blonde but her red hair, along with her raspy voice and comedic talent, has made her famous in movies such as "Superbad," "Zombieland," "Easy A," "Crazy, Stupid, Love" and "The Help."
"I had been blonde my whole life and I dyed it brown when I was 15," Stone told BellaSugar in 2011. "Then when I went to the camera test for Superbad, Martha MacIssac, who was the other girl in the movie, had brown hair. Judd Apatow walked in and said, 'Make it red.' So they took me to a colorist and made my hair red.
"It's just kind of been red ever since, except, you know, when it was blonde for The Amazing Spider-Man. My mom's a redhead. I think maybe there's that, too; the coloring and the association with my mom being a redhead. I really liked that," she added.
Although she's been a redhead in all her movies except for the "Spider-Man" films, Stone has occasionally gone back to her lighter roots, as well as tried out several different haircuts and styles, including bangs.
