Lighten the look of the room, and bring out the deep richness of the brown furniture by painting the walls bright white or adding a white upholstered chair, white curtains and a white throw rug. Add a few throw pillows made of colorful prints on a white background and artwork that continues the theme. The room will be a bright and classic space that is balanced and peaceful.
Use different shades of beige to complement the beige carpet and to contrast with the dark brown furniture. Paint the walls light beige, and use a darker beige or tan on the window frames and woodwork. Cover a few throw pillows in the darker beige color to match the trim around the room. Crown molding painted in a tan color will complete the framing of the room. Add red as the accent color in curtains, an area rug or a couple of accessories, such as a large vase or painting.
If you are hungry for color in a brown-and-beige room, break all the rules, and use bold colors and patterns. Some colors seem to go naturally with brown -- such as blue, peach and gold -- but feel free to use purple, green, yellow or any other color. Use polka-dot pillows or striped curtains. Try a geometric print area rug. Drape a yellow throw across the brown sofa, or use yellow matting in the artwork on the walls. Except for painted walls, the colorful additions can be changed as often as necessary until you achieve the look you want.
A bedroom or dining room with brown wood furniture atop a beige carpet is begging for a little color or a theme to enliven the room and make it more inviting. You can paint walls, use throw rugs, hang curtains and use bed or table linens to add color. A theme or design style can also complete the room. For instance, Victorian design has elements of Oriental and Gothic styles and uses colors such as red, light blue, green, pink, gray and plum. Add a reproduction of a Victorian chair, vintage lamps and an Oriental rug. You can achieve the same results with other design styles.
