What color is Dulux Hawaiian Blue 4?

Dulux Hawaiian Blue 4 50BG 21/328 is a clear, saturated blue-green with a distinctly cool cast, shown here as #0089A3. It has enough depth to hold its own on a full wall, while its crisp teal direction makes it especially effective on bathroom cabinetry, a kitchen island, or a painted front door. In bright daylight, this color is likely to read cleaner and more blue-green, while lower light can make its deeper turquoise character more noticeable. Pair Hawaiian Blue 4 with soft white trim, pale grey tile, natural oak, or warm brass hardware to give the cool color some contrast. For a bolder scheme, use it against inky navy, charcoal, or rich terracotta accents rather than adding several competing bright colors.
