Refreshing Glacier

#31d1df
Notes

Refreshing Glacier (#31D1DF) is a true cyan with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (185°, 73%, 53%) places it in the balanced band at a mid lightness. It works across type, buttons, and borders, saturated enough to feel deliberate but balanced enough to not fight the rest of the palette. For a confident two-color system, pair it with its complementary red. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Refreshing
adjective

Old French refreschir, to make fresh again — present-participle of refresh. As a color modifier, refreshing implies a clear-and-cool-and-revitalizing quality, the crisp color of Cornish-coast and Hebridean-island fresh-sea-air-and-cool-water revitalization. Sits at the crisp-and-cool end of the grid, parallel to fresh and bracing in usage.

Glacier
noun

A compressed mass of ice that has accumulated over decades or centuries — Alpine, Andean, Patagonian, polar. The color refers to the exposed face of a clean glacier where compression has driven out the air: a soft, very pale blue-green with the optical clarity of dense ice. Lighter than aqua, cooler than seafoam, with the high-altitude weight of a landform now retreating across most of the planet.

Moderately saturated colors gain a small bump in P3 — the difference is usually visible side-by-side on wide-gamut hardware but won't change the character of the color.
