Mix and match until you find the color blends that most define who you are and what kind of mood you are in, where you are going and even the kind of people you want to impress.
Do not be afraid to try colors that seem too bright. If one or two bold colors is too much for you, then a single accessory like a necklace or even bracelet of a bright color will make a difference to an otherwise boring look.
Two colors that have a way of blending into each other are black and yellow, not surprisingly because black goes with anything and yellow is the new black for 2012.
