Mapped Arctic

#90effb
Notes

Mapped Arctic (#90EFFB) 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 (187°, 93%, 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

Mapped
adjective

Latin mappa, cloth / napkin — past-participle of map. As a color modifier, mapped implies a clear-and-cartographic-and-surveyed quality, the crisp color of Ordnance-Survey-and-USGS scientific-and-cadastral cartographic-and-topographic mapping-and-projection. Sits at the crisp-and-mapped end of the grid, parallel to plotted and surveyed 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.
