Place throw pillows with black and brown print fabric on the sofa. The black and brown print of the fabric tie together the black sofa and the espresso-colored coffee tables.
Place a black pillar candle holder on each coffee table.
Put a dark brown pillar candle onto/into each pillar candle holder. The black color of the pillar candle holder and the dark brown pillar candles bring together the black of the leather sofa and the espresso color of the coffee tables.
Place a black and dark wood frame with a photograph inside on each table. The combination of the black and the dark wood will tie together the color scheme of the black sofa and the espresso-hued coffee tables. The key is to use accessories that incorporate both colors, tying together the individually colored pieces of furniture for a unified look.
