What color is Dulux Breton Blue?

Dulux Breton Blue 30BB 10/112 is a muted, deep blue with a noticeable grey cast, giving it the character of a weathered slate rather than a bright marine tone. Its low-to-medium brightness helps it read as grounded and substantial on walls, especially in studies, dining rooms, or bedrooms with plenty of natural texture. In daylight, Breton Blue can show its cool blue character more clearly, while evening lighting tends to pull forward its smoky charcoal quality. Use it on cabinetry or a single architectural feature alongside pale oak, brushed nickel, soft white, and warm off-white finishes. For a stronger contrast, pair this shade with chalky beige or muted clay accents rather than crisp, icy whites.
