Make your living room pop with wall art. The right artwork can be the finishing touch on a room and tie all of the living room furniture together. One spot for artwork in the living room is above the sofa. There always seems to be a big empty wall right above the back of the couch. Use horizontal living room wall art to fill that open space while bringing together the different colors in the room. For example, your sofa could be blue while your accent chairs are yellow. If you find artwork that incorporates both colors it will help round out the decor by bridging the color gap.
