Dulux Martian Skies 1 91BB 07/263 is a deep, muted blue with a clear cool cast and a slightly softened, inky character. Its low brightness gives walls a grounded look, while daylight brings out the blue more clearly than it does in the evening. Use Martian Skies 1 in a study, dining room, or bedroom where a darker backdrop can add definition without reading as pure navy. It suits full walls in well-lit rooms, but also makes a strong choice for cabinetry, internal doors, or a fireplace surround. Pair it with chalky off-whites, pale grey-blue tones, natural oak, and brushed brass for contrast that keeps the scheme warm enough to feel lived-in.
