Our brains love visual contrast, so it’s no surprise that its one of the fundamental principles of design. Contrast makes objects distinguishable from each other and their background, and those things with the highest contrast are the first things our eyes jump to when we enter a room. Purple, especially in all its ultra violet glory, makes a sensational colour for a statement piece in a room, whether it be a chair, couch, painting, or feature wall. Keep the rest of the room neutral if you really want it to pop!
