A near-black teal that reads as deep water under overcast sky.
Marine Slate
#1D5C5E
rgb(29, 92, 94)
A muted blue-green with the weight of wet stone.
Harbor Teal
#2E8385
rgb(46, 131, 133)
The palette's working midtone, steady and unhurried.
Tidewater Green
#57A89E
rgb(87, 168, 158)
A brighter aqua that leans toward sunlit shallows.
Seafoam Mist
#8FCBB9
rgb(143, 203, 185)
Pale and airy, like foam thinning across wet sand.
Horizon Cream
#DCEEDF
rgb(220, 238, 223)
A soft green-white standing in for distant sky meeting water.
Driftwood Sand
#E8D9BE
rgb(232, 217, 190)
A warm neutral pulled from bleached wood along the tideline.
Seven colors move together like a single long exposure of shoreline at dusk: dark teal pools at one end, sand-warm neutrals settle at the other, and everything between them stays cool and low-saturation. Nothing here is loud. The greens and blues share enough undertone that they blend rather than compete, so the eye slides across the row instead of snagging on any one swatch. Psychologically the set reads as calm rather than energetic — closer to a held breath than a wave breaking. The single warm neutral, Driftwood Sand, keeps the whole thing from tipping into cold minimalism.

Wellness and spa brands reach for water-adjacent palettes often, but the darker end here — Abyssal Teal and Marine Slate — gives it enough gravity for editorial or hospitality work too, not just skincare packaging. A boutique hotel could run Harbor Teal through signage and Horizon Cream through linens without the story feeling thin. Outdoor gear and coastal real estate branding both benefit from the range between shadow and shallow water, since it lets a logo sit dark on light or light on dark without introducing a new hue. Seafoam Mist and Tidewater Green do well as accent tones in interfaces where a single teal would otherwise feel flat.
Pair Abyssal Teal with Horizon Cream for maximum contrast in headlines and navigation, then let Harbor Teal carry body text or secondary buttons where full black would feel too harsh against the cooler background. Driftwood Sand works as a card background or divider color, giving warm relief between stacked blue-green sections. Keep Seafoam Mist reserved for hover states or thin borders rather than large fills — at scale it can wash out next to the paler neutrals. Because saturation stays consistent across all seven swatches, gradients built from adjacent pairs (Marine Slate into Tidewater Green, for instance) transition smoothly without banding.
