walls: sherwin williams worldly gray... fireplace is calacutta marble... what white for the mantel and trim? I have a really true bright white that really makes the marble look "un" white.... can i use the bright trim for the baseboards and a different white on the mantel? or same white on both? and WHICH white with those tile? I don't want a "cream" color b/c the kitchen cabinets (all one big room) are kraftmaid "dove white"... a cool white, which BTW looks terrible with that bright white also, so i probably can't use that on the window millwork. HELP? thx!
