In the '80s, the typical rock star wore kohl-smudged eyes, teased hair, and a slash of red lipstick. In 2010, it's all about color, color and more color! Think rainbow-hued hair, Crayola-drenched makeup and graphic accessories -- the louder and more cartoony, the better. Whether you're actually a rock star (like Nicki Minaj and Rihanna) or you love to look like one (hello, Amber Rose), this look is playful, fun and here to stay. Go bold or go home!
