Need help with paint color and carpet. Main floor is dark brown hardwood with white trim & crown molding, and carpet will be installed on stairs and second floor. The steps and railings pictured will be restrained to match the dark hardwood floors. We are leaning towards a beige wall throughout. So, what color carpet? Light grey or a beige carpet? Can you mix a grey carpet with a beige wall? Any info/pics of your favorite beige paint color and brand, as well as what specific color carpet to use with would be appreciated! TIA!
