What color is Dulux Noble Grey?

Dulux Noble Grey 30BB 10/019 is a deep charcoal grey with a subtly cool, blue-leaning cast visible in clear daylight. Its low lightness gives walls a grounded, enveloping look, while the restrained saturation keeps it from reading as overtly navy or black. In bright rooms, Noble Grey can show a softer slate character; under warm evening lighting, it tends to appear darker and more neutral. Use it for a study, dining room, feature wall, or painted cabinetry where a strong dark finish is wanted without the flatness of pure black. Pair this shade with crisp off-whites, pale grey-blue tones, light oak, brushed nickel, or natural linen to give the depth some contrast.
