What color is Dulux Sea Urchin 3?

Dulux Sea Urchin 3 90GG 40/115 is a muted blue-green with a noticeable grey cast, giving it a softened, mid-tone appearance. It reads cool and lightly dusty rather than bright, with enough depth to hold its own across larger wall areas. In clear daylight, Sea Urchin 3 shows its blue-green character more clearly, while warmer artificial light can bring out its quieter grey-green side. It suits bathrooms, bedrooms, and calm living spaces, especially alongside off-white trim, pale oak, linen, brushed nickel, and charcoal details. Use this color on walls or painted cabinetry where a restrained wash of colour is wanted without the sharpness of a stronger teal.
