What color is Dulux Royal Regatta 3?

Dulux Royal Regatta 3 39BB 18/351 is a clear mid-tone blue with a cool, lightly teal-leaning cast. Its noticeable saturation gives it enough presence for a feature wall, painted bookcase, or kitchen island without reading as overly dark. In bright daylight, this color can appear cleaner and more open, while lower or warmer artificial light may bring out its deeper blue character. Pair Royal Regatta 3 with crisp white trim, pale grey, sandy beige, or light oak to keep the scheme grounded. Brushed nickel, matte black hardware, and natural linen also suit its fresh, architectural look.
