What color is Dulux Niagara Blues 3?

Dulux Niagara Blues 3 10BB 40/090 is a light, muted blue with a noticeable grey cast that keeps it soft rather than bright. Its cool character suits bedrooms, bathrooms, and north-facing rooms where a calm, airy wall color is wanted without a stark white finish. In daylight, Niagara Blues 3 reads as a gentle blue-grey; under warmer evening lighting, its grey undertone becomes more apparent. Pair it with crisp white trim, pale oak, brushed nickel, and charcoal details for a clean, understated scheme. It is particularly effective across full walls or on painted cabinetry where its low saturation can provide color without dominating the room.
