A dark blue bedroom design looks chic and intimate as long as the room is balanced with brighter hues. Choose dark blue wall color and pair it with white, cream or light gray bed sheets and furniture pieces. In addition to that, use mirrors, warm lights and natural wood accents in your design to brighten up the bedroom. Don't overload the room with heavy decoration items and try to let more natural light into the room. A thought-out dark blue bedroom design will create a chic atmosphere without making the room small and dark.
