Sorry, I pressed 'submit' by error so my title doesnt make sense. I am looking for wall color suggestions (any recommendation for rugs would be appreciated as well).

We have Brazilian cherry floors in our living/dining/kithchen area - not something we would have chosen, but they are in a very good shape and we won't be changing them for at least a few years. We also have Crate and Barrel lounge sectional in walnut (dark brown). Anu suggestions for wall color and/or rug? The staircase is painted SW sand trap and it looks ok (but doesn't have a big dark sectional in it).
