My quilt room is very small (7x8), with 2 large windows and much of the wall space is occupied with drawers and racks. For me, White was the only possible choice.
My kids had 'captains' beds, with drawer under. All the drawer units became fabric storage when they were gone from home. In a previous sewing room (20x24, boy do I wish I had that one now!), I used kitchen cabinets and counters other people had replaced. Unless you have a very small stash, the background color may not matter.
