Brown carpet can add richness to a room and can stand up to deep-colored furnishings, such as Victorian-style furniture, that could overwhelm a softer-colored carpet. It is also easier to keep clean-looking than a light-neutral color like beige, but it can be tricky to work with when decorating a room; it's a strong color and can make a room look less bright, lending a heavy look if you're not careful how you balance it with other elements
Select furniture of a color and style that complements the carpet. This is the right place for your Victorian or Arts and Crafts furniture or heavier, more colorful or more distinctive pieces of modern furniture. Choose pieces with strong design elements. Avoid furniture that is light--not just in color, but in shape; small, delicate pieces tend to look overwhelmed. Smart furniture colors are green, red, yellow, brown, black, navy blue, and, for a retro '70's look, small amounts of orange.
Apply wallpapers, wall coverings or paint that complement the brown carpeting. For a Victorian room, use wood paneling or a textured wallpaper, especially in a William Morris reproduction design or a simple damask. For a modern room, paint the walls a rich, yet bright color such as yellow or hang wallpaper with simple, strong geometric designs.
Textiles should carry out the richly colored, bold theme. Use textured fabrics in similar colors to furnishings and wallpapers, adding a few brighter touches with throws and pillows to liven up the color themes and keep the room from looking too somber. A few fuchsia throw pillows or a bright crazy quilt can do much to make a room pop.
Adding Area Rugs
If the carpet is not coordinating well with your existing furniture, add some patterned area rugs in coordinating colors. Use floral patterns in warm colors for traditional or Victorian decor or geometric patterns for modern decor. Avoid adding patterned rugs if the walls are a bold color or pattern; too many patterns in a single room, especially in strong colors, looks too busy. Solid, lighter colors are a good bet if working with bold walls.
