Brands using this color
Palettes built around it
Clinic
Open in tool →Teal reads clinical without the coldness of pure blue; the coral accent adds warmth for reassurance moments.
Alpine
Open in tool →Glacier blue with a safety-orange accent: technical outdoor gear, not lifestyle.
Coastal
Open in tool →Sea-teal, sky and sand — bright without shouting; works for travel, wellness, and anything near water.
Paper & Pine
Open in tool →Deep pine on paper-white with a marmalade accent — a quiet, sustainable-brand palette that isn't beige.
Laser
Open in tool →Laser green, violet and cyan — the synthwave/gaming set; keep the type near-white and let one neon own each screen.
Glacier
Open in tool →Three blues from ice to deep water on a pale surface — a monochromatic winter set with real depth.
Frost & Ember
Open in tool →Navy and frost with one ember red — the classic cold-with-a-warm-accent structure, borrowed from a thousand ski posters.
Meadow
Open in tool →Fresh green, buttercup and a wildflower pink — spring at full saturation; the leaf-dark text does the anchoring.
Rain Garden
Open in tool →Wet-leaf teal and moss with a soft peach — an overcast spring, calmer than the bright version and better for long reading.
Tide Pool
Open in tool →Sea-green and slate with a coral — a literal tide pool: two cool tones, one warm creature.
Harbour
Open in tool →Steel blue and haze with a buoy orange on a pale grey — the maritime palette every port town uses for a reason.
Canopy
Open in tool →Deep green and new-leaf mint with a bark-pink accent — a forest that reads calm rather than camo.
Blue Mono
Open in tool →One blue at four lightnesses — monochromatic in the colour-theory sense; the deep step is the text, the pale step the surface tint.
Stone
Open in tool →Stone greys with a faint warmth — Tailwind's stone scale used as a whole palette: interfaces that want to disappear.
Still Water
Open in tool →Dusty teal and mist with a sand accent — low chroma, low contrast between colours, high contrast for text: the recipe for calm.
Dusty Blue
Open in tool →Dusty blue and mist with a nude accent — the quiet wedding palette; nothing here competes with a photograph.
