What color is Dulux Royal Regatta 4?
Dulux Royal Regatta 4 31BB 23/340 is a clear mid-tone blue with a subtle cyan cast, based on its #3F87BC color value. It has a cool, fresh appearance without becoming overly dark, making it a strong option for a bedroom wall, bathroom cabinetry, or a painted front door. In bright daylight, Royal Regatta 4 reads as a clean blue, while warmer indoor lighting can soften its crispness slightly. Pair it with soft white trim, pale grey, light oak, or brushed nickel for a clean-lined look. For more contrast, use it alongside deep navy details or warm terracotta and rust-toned accessories.
