Tidy Arctic

#90eff4
Notes

Tidy Arctic (#90EFF4) 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 (183°, 82%, 76%) 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

Tidy
adjective

Old English tidig, timely — drifted in modern English to mean neat, orderly. Used as a color modifier for hues that read as composed and unfussy. Tidy beige, tidy gray: moderate saturation combined with optical neatness. Sits at the crisp-bucket alongside plain and modest.

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.

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.
