What color is Dulux Blue Diamond 5?

Dulux Blue Diamond 5 is a light blue-green with a clear aqua cast, sitting between a soft sky blue and a muted turquoise. Its medium-light value keeps it fresh on broad walls without reading icy, while the green undertone gives it more presence than a conventional pale blue. In bright daylight, this color can appear cleaner and bluer; under warmer artificial lighting, its turquoise side is likely to become more noticeable. It suits bathrooms, kitchens, sunrooms, or a child’s bedroom, and can also make painted cabinetry feel crisp rather than heavy. Pair Blue Diamond 5 with warm white, pale oak, sandy neutrals, brushed nickel, or deep charcoal accents for contrast.
