Acidic Yanagi

#67a81f
Notes

Acidic Yanagi (#67A81F) is a true lime 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 (88°, 69%, 39%) places it in the balanced 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 indigo. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Acidic
adjective

Latin acidus, sour — adjectival suffix -ic, sharing root with acetic and acerbic. As a color modifier, acidic implies a saturated-and-citric-and-sour quality, the bright color of lime-zest-and-pickled-lime citrus-fruit pulp surface. Sits at the bright-and-cool end of the grid, parallel to acid and electric in usage.

Yanagi
noun

Salix — the willow in Japanese, and the soft yellow-green of fresh willow leaves in spring. Yanagi-iro is a traditional Japanese fashion color, distinct from moegi by its slightly cooler shift. The color refers to a fresh willow leaf along a Kyoto canal: a soft, slightly cool yellow-green with the satin finish of new lanceolate foliage.
