"Zillow® research finds that today's buyers are drawn to warm, grounded interiors over all-white walls," said a company news release earlier this week. "In the living room, pale blue commands $1,723 more than white, and charcoal gray $1,509 more. In the bedroom, it's not just chocolate brown that beats white [by $2,277]. Charcoal gray also commands higher offers, by $1,240, and sage green tops white by $1,035." Of course, interior design colors come in and out of fashion.
