Dulux Neptune Seas 78GG 19/078

Dulux Neptune Seas 78GG 19/078 is a muted blue-green with a noticeable grey cast, giving it a grounded, low-saturation appearance. Its mid-to-deep value helps it read as substantial on walls without becoming as heavy as a charcoal or navy. In cool daylight, Neptune Seas can show more of its blue-green side, while warmer bulbs tend to draw out its softened, smoky quality. It suits a bathroom, study, or dining room where a darker color is wanted with some color still visible. Pair it with warm off-whites, pale oak, brushed brass, or natural linen to keep the scheme from feeling too cool. On cabinetry or a single accent wall, this shade adds definition alongside lighter neutral walls.
