We're lucky enough to have a really big bedroom with a bay window and high ceilings. It's been beige since we moved in a year ago as other bits of the house took priority but I'm ready to do it now. I like the idea of dark walls, such as the dark teal in the attached pic, but am not sure if we should do all the walls and whether we go above the picture rail as well as below, and whether the ceiling should be dark too. Bay will have patterned roman blinds with a pale background, we'll have a pale rug and our bedding will be white.
