What color is Dulux Smooth Flint?

Dulux Smooth Flint is a light, muted grey with a faint cool blue cast visible in its #B2B8B9 color value. It sits at an easy mid-light depth, giving walls definition without making a room feel closed in. In daylight, Smooth Flint can read as a soft blue-grey, while warmer artificial lighting may bring out its more neutral grey side. It suits bathrooms, kitchens, and contemporary living rooms, particularly alongside crisp white trim, pale oak, brushed nickel, and charcoal details. Use it across full walls for a calm, lightly structured backdrop, or on cabinetry where its understated coolness can sharpen warmer materials.
