Michelle Saunders painted nails with Essie Power Clutch, a dark gray with green undertones. "It's inspired by menswear: a gray tweed suit," she explained. "When you put a neutral gray on the hands, it just lets everything else in the collection shine."
And if you want to find the perfect gray for your needs, follow Saunders's rule: "It's less based on skin tone and more based on season," she said. "As we go into Fall and Winter, you can do dark gray and you can do the green-grays, and in Spring and Summer, you can do a lighter pastel gray, almost like a mint gray."
