What color is Dulux Starlit Night 1?

Dulux Starlit Night 1 70BB 09/241 is a deep, muted blue with a clear cool cast and a slightly softened, slate-like quality. Its mid-dark depth gives walls definition without reading as near-black, especially in rooms with good natural light. In brighter daylight, this color can appear cleaner and more blue; under warm evening lighting, it tends to look deeper and more subdued. Use it on a study wall, dining room, hallway, or painted cabinetry where a stronger color is wanted without excessive brightness. Pair Starlit Night 1 with chalky white, pale grey, natural oak, brushed nickel, or warm tan leather for contrast.
