Paint all the walls red, only one wall red with the others white, or use a combination of both colors. For example, use solid red on the lower one-third of the walls with a red and white pattern, such as stripes, wavy lines, circles, damask or floral patterns, on the top two-thirds of the walls. Patterned wallpaper is another idea.
Introduce a solid neutral color in the room through your furniture if you don't want everything to be red and white, such as light, natural wood, chocolate brown or black. Combine the neutral-colored furniture with red and white furniture for a complete look, such as a chocolate brown pedestal and glass dining table with red chairs and a white hutch in a dining room or a black wrought-iron bed, black nightstands and a white-and-red patterned chair in the bedroom.
Weave red and white throughout the room with fabric and textiles. Include a third accent color if you desire, such as a neutral chocolate, daring aqua or sweet pink. White curtains with red circles and a matching rug go together in a modern living room or bedroom. Pair red sheets with a white comforter that has a red pattern embroidered on it, and add a few red pillows. White towels with a red rose pattern work well in a bathroom.
Hang artwork, mirrors or pictures on the red walls to break up the loud color and spark interest in the room. Use the artwork to unite the entire color scheme. Black-and-white photos in black frames can pop off the red walls without detracting from the red and white color scheme.
Accessorize the room with at least one bold or bright piece, even if it's also red and white, such as a zebra print rug or huge wrought-iron sculpture. Sprinkle small pieces, such as a lamp, vase and throw, in the room in an accent color, such as black, pink, lime green, turquoise or silver. A vibrant color adds visual interest, as long as it's used sparingly.
