Sophisticates are likely happier with a cool-to-medium shade of gray serving as a backdrop to their red sofa. Light teal or blue walls provides a retro look for the throwback designer. White walls create a contemporary aesthetic when paired with bright cherry-red leather furniture and geometric designs in curtains and accessories. Wood-tone walls blend comfortably with deeper reds such as mahogany or antique ruby. Bold wall colors work best as an accent wall opposite a red couch, with neutral tones throughout the rest of the room.
