One option for decorating a room with a yellow couch is to use a monochromatic color scheme. It is an ideal option when using a bold color such as yellow because varying shades of yellow add dimension to the room while keeping the look from becoming too bright. If your sofa is a bright lemon yellow, opt for a lighter tone for the walls. For a light butter-colored sofa, try a deep golden wall color. You can incorporate other shades, such as red, blue, green and brown, as accent colors throughout the room to break up all the yellow.
If you want to make your yellow sofa the focal point of the room, opt for a neutral color for the walls. White paint creates a fresh, crisp look when paired with a yellow sofa and instantly brightens the room. If you prefer a look that is less stark, go with a cream or beige shade. These colors are softer than white, and have yellow undertones so they are an ideal complement to the sofa. Tan provides a darker, richer tone for the walls that still pairs well with a yellow sofa. For a unique, modern look, try a light gray on the walls to highlight a yellow sofa.
For a comfortable, homey look, pair your yellow sofa with a warm wall color. Yellow is a warm color itself, so it is complemented by similar tones. Using a color palette of entirely warm tones creates a cozy, inviting feel that is ideal for a living room or family room. For a subtle look, pair peach-colored walls with a golden yellow couch. You can try a richer shade such as terra cotta or rust for the walls if you prefer a bolder look. Sage green walls also provide a warm compliment to a yellow sofa and give the room a soft, soothing feel.
For a truly bold look, choose a cool wall color that contrasts with the warm tones in your yellow sofa. A soft sky blue and blue-gray are subtle options, while an indigo shade adds instant drama to the room. If you prefer an elegant, sophisticated look, pair your yellow sofa with rich navy blue walls. Other jewel tones such as emerald green or eggplant provide a similar look.
