Caffeinated Auvergne

#83b838
Notes

Caffeinated Auvergne (#83B838) is a true lime with an earthy character. It leans grounded and natural, the kind of color that plays well with wood, clay, linen, and warm neutrals. Its HSL profile (85°, 53%, 47%) 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

Caffeinated
adjective

Modern French caféine — past-participle of caffeinate. As a color modifier, caffeinated implies a saturated-and-jumpy-and-active quality, the bright color of Red-Bull-and-Monster energy-drink-can label-design saturated-and-energizing palette. Sits at the bright-and-active end of the grid, parallel to jazzed and wired in usage.

Auvergne
noun

The volcanic central French region — and the deep green of Auvergne plateau pasture, Salers cattle grazing land, and the green moss of volcanic-rock walls. Auvergne refers to an Auvergne montagne in early summer: a saturated, slightly muted deep yellow-green with the matte finish of volcanic-soil grass.
