If you're looking for a photo to take to the salon to help your hair colorist envision your perfect light-brown hair color, this photo of Kate Beckinsale taken on the set of her new movie Absolutely Anything is a strong contender.
Several things make Beckinsale's color (done by colorist Tracey Cunningham) exceptional: There's tons of dimensions (thanks to Cunningham's three-colors-plus-a-gloss technique), there's not a hint of brassiness, and the change in tone between her roots and her ends is the perfect one full step to make her look a bit ombre—but not too much.
This is light brown ombre hair color done 100 percent right. And Cunningham herself has said it's crucial to bring a photo in with you to make sure you and your stylist are envisioning the same thing, so bookmark this one for later. Then read our interview with the colorist and get all sorts of genius tips for making sure your next trip to the salon is a success.
