Refreshing Arctic

#90f1f9
Notes

Refreshing Arctic (#90F1F9) is a soft cyan with a cool character. It leans cool, sitting on the blue, green, and violet side of the wheel. Quiet and dependable, a fit for product UI and data visualization. Its HSL profile (185°, 90%, 77%) places it in the highly saturated band at a light lightness. Best used in small doses, like logos, CTAs, focus rings, or highlight text, where its saturation becomes a feature rather than noise. 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.

Arctic
noun

Greek ἄρκτος (árktos, bear) — used in geography for the Arctic-Circle northernmost-temperate-zone, particularly the iconic pure-white Ursus maritimus (polar bear) and Vulpes lagopus (Arctic fox). Arctic color refers to an Ursus maritimus in mid-winter pelage on Svalbard pack-ice: a pure white with the matte finish of pure-white melanin-depleted bear-fur against pack-ice substrate.
