KEY COLOR NOTES If it's not natural, flame red hair can look costumey against nearly any complexion. But a coppery auburn with a wash of strawberry highlights like Stone's is flattering on skintones ranging from ultra-fair to tan and tawny. (Skip the shade if you're olive or darker.) And do take a tip from the star by asking that your brows be touched-up, too. The simple tweak enhances the overall sexiness of the shade.
