Dulux Chalk Dust 10BB 83/017

Dulux Chalk Dust 10BB 83/017 is a very light, low-saturation off-white with a subtle cool blue-grey cast. Its high brightness keeps walls looking clean and airy, while the slight grey content prevents it from reading as stark white. In daylight, Chalk Dust can appear crisp and softly mineral; under warmer lamps, its cool edge is likely to soften into a quieter pale grey. It suits bedrooms, bathrooms, and light-filled living rooms, especially alongside pale oak, brushed nickel, white ceramics, and charcoal details. Use it across broad wall areas or on cabinetry when you want a gentle contrast with warmer whites and natural wood.
