Talk about a quick change. After spending a few weeks as a platinum blonde, Rooney Mara was spotted out in West Hollywood yesterday in her old-school hue. Considering her penchant for a graphic updo, we were pretty excited at the possibilities her pale strands held, but it's no surprise that her darker tone is just as gorgeous, especially since it's been her signature for so long. And she's in good company—just last week, Emma Stone finished a similar hair color journey, which started at red, shifted to deep brunette and platinum blonde, only to go right back to red.
