Just a little bit of brown can go a long way in a living room’s design. Cocoa brown and soft pastels are pretty accents in this living room that’s grounded by white walls. Designer Mariah O’Brien loves using white as a backdrop for a room with a variety of other elements like rich shades. “The white really makes an impact, as it’s a perfect backdrop for the other design elements we brought into the living experience," O'Brien says. Cocoa chairs and curtains add just a touch of brown to a room filled with pretty pastels.
