What color is Dulux Restful Slumber?

Dulux Restful Slumber 30BB 45/049 is a light, muted blue-grey with a softly cool cast and low saturation. Its pale grey base keeps the blue understated, so it reads calm and airy rather than overtly colourful. In bright daylight, this color can appear cleaner and slightly bluer, while lower or warmer artificial light brings forward its gentle silvery-grey side. It suits bedrooms, bathrooms, and light-filled living spaces where a quiet wall color is wanted without using plain white. Pair Restful Slumber with crisp white trim, pale oak, brushed nickel, charcoal accents, or soft off-white textiles for a restrained, layered finish.
