What color is Dulux Imperial Mauve 1?

Dulux Imperial Mauve 1 70BB 21/147 is a muted blue-grey with a noticeable violet cast, giving it the look of a softened slate rather than a bright purple. Its medium-dark depth makes it particularly effective for bedrooms, studies, and dining rooms where a stronger wall color can add definition without feeling overly heavy. In daylight, the grey-blue character is likely to read most clearly, while warmer evening lighting can bring its subdued mauve undertone forward. Pair Imperial Mauve 1 with chalky white trim, pale grey textiles, and light oak for a clean contrast, or use it alongside charcoal, brushed nickel, and deep navy for a more layered scheme. It also suits fitted cabinetry or a single accent wall when a cool, grounded color is needed.
