Open Arctic

#97ecee
Notes

Open Arctic (#97ECEE) 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 (181°, 72%, 76%) places it in the balanced band at a light lightness. It works as a background wash, large-area fill, or soft illustration tone. Add a darker ink of the same hue when you need type over it. 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

Open
adjective

Old English open, unobstructed — used as a color modifier since the eighteenth century for hues that read as airy or uncrowded. Open blue, open green: moderate saturation combined with optical spaciousness, the slight visual breath of a hue that doesn't crowd the surface it covers. Sits at the crisp-bucket center alongside clear.

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.
