What color is Dulux Sea Holly?

Dulux Sea Holly 30BG 10/111 is a deep, muted blue-green with a distinctly cool cast and a smoky greyed quality. Its low-light depth makes it especially effective on cabinetry, a study wall, or an exterior front door where a stronger color is wanted without a bright finish. In daylight, Sea Holly can read as a restrained teal, while dimmer rooms may bring out its darker blue-grey side. Pair it with soft off-whites, pale stone, weathered oak, and brushed nickel for a clean, grounded scheme. For more contrast, use warm clay accents or aged brass hardware to offset this color’s cool depth.
