Atmospheric Forgetmenot

#87acb9
Notes

Atmospheric Forgetmenot (#87ACB9) 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 (196°, 26%, 63%) 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 orange. 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.

Forgetmenot
noun

Myosotis sylvatica, the European forget-me-not — a small woodland-and-streamside wildflower whose pale blue five-petaled flowers symbolize remembrance and faithful love in European folk tradition. The color refers to a fresh forget-me-not flower: a soft, slightly cool pale blue with the matte finish of small five-petaled flower with yellow center.
