Cool down this Summer with peppermint . . . nail polish, that is. For several stars, the soft but noticeable hue has provided a light-hearted way to accentuate this season's warm-weather styles. Wear it with muted clothing à la Anna Kendrick (left) for a pop of color, or take it up high-octane with a vivid yellow frock, just like Brooke Burke (lower right). And for a look worthy of any music festival, apply eye-catching orange paint on your fingers, Santigold-style (as seen in the upper right). Whatever you choose, you're bound to make a refreshing statement.
