I love brown sofas. Keep the walls lighter, anchor the space with a light-color textural rug, and limit other dark browns to an accent chair or a picture frame. Bring in midtones such as hot pink, red, and teal.
Mix and match textures in your living room for a personal take on modern style. A woven tray will warm up a marble coffee table and stylishly display personal pieces, plants, or geometric candle votives. Bonus: it's easy to move when entertaining.
