Truthful Arctic

#91f2fb
Notes

Truthful Arctic (#91F2FB) is a soft cyan with a pastel character. It reads calm and airy, with enough chroma to feel intentional rather than washed out. Its HSL profile (185°, 93%, 78%) 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

Truthful
adjective

Old English trēowth, truth — adjectival suffix -ful. As a color modifier, truthful implies a clear-and-honest-and-direct quality where the hue carries the visual register of accurate-and-faithful-representation declaration. Sits at the crisp-and-honest end of the grid, parallel to candid and honest 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.
