What color is Dulux Cobalt Embrace?
Dulux Cobalt Embrace 43BB 09/340 is a deep, saturated blue with a noticeably cool, slightly teal-leaning cast. Its dark value gives it real presence on a feature wall, built-in cabinetry, or a front door, while daylight brings out the clearer blue in the color. In lower light, Cobalt Embrace can read as a more shadowy navy-blue, making it especially effective in rooms with pale trim or warm lighting. Pair it with crisp white, soft grey, natural oak, brass, or tan leather to create contrast without losing its depth.
