Michelle Williams is happy that the world noticed her new hair color, though her update wasn’t meant to shock. “I don't even know that it was a conscious choice,” the Golden Globes Best Actress nominee told us at the Forevermark and InStyle-hosted cocktail party in Beverly Hills last night. “I kept cutting it shorter and shorter and as a result it got darker and darker. It naturally happened.” Her colorist Marie Robinson seconds her story. “It’s more golden and honey, but she was platinum for so long it looks pretty strawberry to everyone,” Robinson told "To show off the texture in her haircut, I used several different lowlights, with a golden blond at the roots and warm blond on the ends." Williams noted, however, there could be one more reason for her new hue: “You know what it is? It's because my hair never sees the sun because it lives under wigs most of the time! That's what it is!” Either way, great look!
