What color is Dulux Blue Diamond 1?

Dulux Blue Diamond 1 is a deep blue-green with a clear teal cast and a cool, shaded character. Its strong depth makes it especially effective on cabinetry, a dining room wall, or a front door where the color can hold its own against pale surroundings. In bright daylight, Blue Diamond 1 reads as a clean, inky teal, while lower light brings out its darker, more enveloping side. Pair it with warm white trim, pale oak, brushed brass, or terracotta-toned accessories to bring contrast and warmth. For a more tonal scheme, use it alongside soft blue-greys and muted green accents.
