For Spring 2012, designers dipped their collections into every shade and vibrancy of the Roy G. Biv spectrum. Simply put, it's all about placing your favorite colors on blast. From ladylike pastel pinks at Rochas and powdery floral blues at Erdem, to electric greens at Jean-Paul Gaultier and soft lemon iterations spotted at Jason Wu, it's safe to say where there's color, there's a way to wear it. We've rounded up the prettiest blues, reds, purples, and more to pop up on the runways and taken care to hone in on the coolest color combos we've seen this season. Time to put those chic black pieces away (for now), and click through to see which rainbow-inspired shade you'll be donning for Spring.
