What color is Dulux Free Dive?

Dulux Free Dive 27BB 21/366 is a clear, medium-depth blue with a noticeable blue-green lean and a clean, lively level of saturation. It has enough depth for a full wall in a bathroom, home office, or child’s room, while still reading fresh rather than heavy. In bright natural light, this color shows its crisp aquatic character; under warmer evening lighting, it can appear deeper and slightly more muted. Pair Free Dive with soft white trim, pale grey, light oak, or woven natural fibres to keep the scheme grounded. It also makes a strong choice for a painted front door, built-in shelving, or a single accent wall against quieter neutrals.
