What color is Dulux Blue Lagoon?

Dulux Blue Lagoon is a light, clear blue with a cool cast and enough softness to avoid looking overly bright. Its gently muted finish gives walls a clean, open appearance, especially in bedrooms, bathrooms, and light-filled living spaces. In daylight, Blue Lagoon reads as a fresh sky-blue; under warmer artificial light, it can appear quieter and slightly more softened. Pair it with crisp white trim for contrast, or use pale oak, woven linen, and soft grey textiles to bring out its relaxed, airy character. It also makes a polished choice for a painted cabinet or interior door when set against warm neutrals.
