Dulux Niagara Blues 4 / Nordic Seas / 10BB 55/065

Dulux Niagara Blues 4 10BB 55/065 is a light, muted blue-grey with a noticeably cool cast and soft greyed depth. Its low-key saturation keeps it from reading as a bright sky blue, giving walls a calm, lightly weathered appearance instead. In daylight, the blue tone is likely to appear clearer, while warmer artificial light can draw attention to its grey side. Niagara Blues 4 suits bedrooms, bathrooms, and quiet living areas, particularly alongside crisp white trim, pale oak, brushed nickel, or charcoal details. It can also make a restrained choice for cabinetry when paired with warm stone or off-white walls.
