I don't think I need to tell you that a certain beigey-gray shade is hot for Spring. The shade, which has just a hint of purple, is perfect if you love your polish to be neutral. But if you're looking to do purple in a more notice-me kind of way, you've got options. Take Kelly Osbourne and Keke Palmer, who recently wore low-key matte-toned versions of the icy hue. If it's more flash that you're longing for, think metallics and glitters à la Katy Perry at the 2010 Kids' Choice Awards. Regardless of which finish you choose, keep the following tips in mind: light, matte shades tend to look best on shorter nails, while bold, dark shades are a great option for longer nails.
