I always wanted to use grey as the main color. I have Sherwin-Williams, Rock Candy for the wall color throughout my brand new house, I just LOVE how it plays up any color you put with it. The interior decorator was skeptical. But, I'm really pleased with the outcome. She 'suggested....' some kind of tan...I find the under tone of grey to be soothing. And, even though the interior decorator, thought it would clash with the hardwood oak flooring,,it does not. I extremely happy with the outcome.
