Atmospheric Mizu

#87a6ae
Notes

Atmospheric Mizu (#87A6AE) is a true 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 (192°, 19%, 61%) places it in the muted band at a mid lightness. It works across type, buttons, and borders, saturated enough to feel deliberate but balanced enough to not fight the rest of the palette. 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

Atmospheric
adjective

Greek atmós (vapor) plus spaira (sphere) — adjectival suffix -ic. As a color modifier, atmospheric implies a pale-and-air-and-mood-and-environmental quality, the pale color of Romantic-period-and-Tonalist landscape-painting atmospheric-and-mood-evoking soft-light surface. Sits at the pale-and-soft end of the grid, parallel to vaporous and misty in usage.

Mizu
noun

The Japanese word for water — used as a color word for the saturated pale blue of fresh spring water and the mizu-iro of traditional kimono linings. Mizu spans the cyan-blue boundary in Japanese color vocabulary. The color refers to fresh spring water in a Kyoto stone basin: a soft, slightly cool pale blue with the optical clarity of cold mineral water.
