What color is Dulux Basically Black?
Dulux Basically Black 42BB 09/032 is a deep charcoal grey with a noticeable cool, blue-grey cast rather than a flat, inky black. Its softened depth makes it a practical option for feature walls, fitted cabinetry, interior doors, or a study where a darker finish is wanted without losing all visible detail. In bright daylight, the grey-blue character is clearer, while evening lighting can make this shade read closer to near-black. Pair Basically Black with clean off-whites, pale concrete tones, brushed steel, or light oak to sharpen its cool character. Against warmer timber, brass, and tan leather, it creates a more grounded contrast.
