What color is Dulux Mystical Night?

Dulux Mystical Night 67BB 09/166 is a deep, muted blue with a noticeable slate-gray cast. Its low brightness gives walls a grounded, enclosing look, while the blue keeps it from reading as flat charcoal. In bright daylight, this color can appear clearer and slightly cooler; under warm evening lighting, its gray depth becomes more pronounced. It suits studies, dining rooms, bedrooms, and hallway accents, particularly when paired with soft off-whites, weathered oak, brushed brass, or warm tan leather. Mystical Night also makes a strong choice for painted cabinetry or a front door where a dark blue feels more nuanced than black.
