A black rug or gray rug puts a final touch to a room with a black/white or tone on tone color scheme. Grey rugs can vary in shades from the palest of gray bordering on white to the deep dark color of underbelly of storm clouds. Neutral in tone, a grey wool rug will anchor a room while letting the furnishings or artwork provide the color or supply another layer in a tone on tone palate. A black oriental rug appears most at home when teamed with bright colored furniture and accessories or with white and grays. Grey area rugs or black area carpets if properly cared for, will last many years beautifying your home.
