I have painted the ceilings of my master bedroom BM "ceiling white" and am looking for advice regarding the walls. I want them to be white as well but should their be a definition with paint finish i.e. pearl, satin or other to distinguish between ceiling and wall? Should I choose a "different white"? Or, try to match as close to "ceiling white" as possible? There is no crown molding - its a cape and there are too many strange angles.
