So, having a neutral base color in your wedding color scheme is a pretty common thing. Most brides choose to have a neutral to ground their theme, and then accent (either lightly or heavily) with brighter colors. 2010 was the year of gray. Gray was by far the most popular wedding neutral, with the color combos of gray + yellow and gray + red dominating the wedding scene.
For 2011, brown is the new gray. Which is funny, because gray was the new brown. So I guess brown is making a comeback. In 2008-9 chocolate brown was the IT neutral for weddings, and for 2011 it's coming back strong. But also, mocha, latte, and taupe are coming back with brown, as a lighter, more airy alternative to dark chocolate brown.
