Dulux Celestial Blue 1 81BG 09/241 is a deep, cool blue with a clear teal cast, reflected in its rich #00546E tone. It has enough depth to ground a room without reading as near-black, making it particularly effective on a feature wall, built-in shelving, or painted cabinetry. In brighter light, its blue-green character is more apparent; lower light brings out its darker, inkier side. Pair Celestial Blue 1 with crisp white trim, pale grey, warm off-white, or natural oak to give the color contrast and definition. Brushed brass, black metal, and light stone surfaces also sit comfortably alongside this shade.
