I love deep, darker colors in some rooms, for me they seem to create a more relaxing environment. My office is a deep, dark blue and I love it. However, when I designed my sewing room I knew that use of dark saturated color would impact how fabrics looked on the design walls. Since white rooms are too stark for me, so I ended up picking a neutral color for the walls, Home Depot's Ralph Lauren brand in "Oatmeal" color, and then painted the ceiling a very bright white to bounce the light back down. It has worked out well for me.
