My sewing room is the white with a hint of blue in it, but I have a closet with sliding doors that go the width of the room and they are painted a very pale yellow. Luckily I have a wall of windows to let the sun in - not a great view out there but having the sun to light the room makes it for truer colors of the fabric.
Do what you like - and what keeps you being creative, that is what really matters. The quilts are just temporary residents of the area.
