What color is Dulux Blue Diamond 3?
Dulux Blue Diamond 3 is a medium-deep teal with a clear blue-green cast and enough saturation to hold its own on a large wall. Its cool character reads bluer in daylight, while warmer bulbs can bring out a slightly greener, more softened side. Use it in a bathroom, study, or dining area where a stronger wall color can add definition without appearing nearly black. Blue Diamond 3 pairs well with crisp white trim, pale oak, brushed nickel, and chalky light grey, or with warm clay and sand tones for more contrast. It is especially effective on cabinetry, a feature wall, or exterior details such as a front door.
