Place contrasting throw pillows on the brown couch. Choose plaids with differing shades of red or yellow and alternate them with beige or cream-colored pillows.
Toss a quilt with multi-colors across the back of the couch or on one end. The brown couch offers a rich background to highlight the craftsmanship of the quilt.
Pair the brown couch with white, green or orange chairs that sit facing the sofa or place a cream-colored rug in front of the brown couch. The light or contrasting colors coupled with the dark couch play off each other, with one highlighting the other.
Group oak wood furniture, such as end tables or a coffee table, around the brown couch. The wood furniture along with the brown sofa continues the rich, bold theme.
Paint the wall behind a brown couch a flattering lighter shade such a light gray or slate color. Lighter wall shadings provide a rich backdrop for a brown sofa.
Place dark colored lampshades, such as red, on end tables next to the brown couch. Fringe or beads lining the lampshade bottom offers a distinctive touch that softens the boldness of a large piece of furniture.
