What color is Dulux Smokey Slate?

Dulux Smokey Slate is a muted, medium-dark blue-grey with a cool, softly weathered cast. Its low saturation keeps it from reading as strongly blue, so it can look closer to charcoal grey in dim rooms or under warm evening lighting. In brighter daylight, the blue undertone becomes clearer and gives walls a crisp, grounded presence. Smokey Slate suits studies, bedrooms, hallways, and exterior details where a deeper neutral is wanted without the heaviness of near-black. Pair it with soft off-whites, pale grey, natural oak, brushed steel, or black metal for a clean, restrained finish.

What are Dulux Smokey Slate undertones?

Smokey Slate is a midtone, near-neutral charcoal gray. Its chroma is so low that assigning a specific hue-based undertone would be misleading. Because it is close to neutral, nearby surfaces and the color of the light can noticeably change how warm or cool it appears.
