What color is Dulux Black Opal?

Dulux Black Opal 66BB 06/077 is a deep blue-charcoal with a distinctly cool cast, reading almost black in low light while retaining a muted navy presence in brighter rooms. Its low-light value gives walls real visual weight, making it especially effective in studies, dining rooms, or a bedroom used mainly in the evening. On cabinetry or interior doors, Black Opal creates a crisp contrast against soft white walls and pale limestone or oak finishes. Pair it with chalky greys, cool off-whites, brushed nickel, and natural timber to keep the scheme clear rather than overly dark. In sunlit spaces, the blue undertone is likely to show more clearly, while warm artificial lighting can make this shade appear softer and more charcoal-led.
