Taza from Tuftex Carpets of California on the stairs! Very pretty! carpet on stairs
Another option is too choose a gray carpet with a pattern. Unfortunately the affordable ones usually don't have a large scale pattern like the rugs we're looking at. Carpet Westbay - 52V46 - Clear Water - Flooring by Shaw
I love this carpet texture - Martha Stewart's Winterthur pattern; the big sample is Brook Trout.
