[jajaykumar]

...cherry hardwood floor? I am planning to paint my walls. I have furniture that is dark brown in color, leather sofas dark brown in color (natural leather color) and having an open kitchen facing family room with tachoma hazelnut cabinets (closer to cherry color). The hardwood floors is reddish brown in color. I have a plan to put a rug in front of the sofas. What color do you recommend for that as well? Thanks in advance.
