Beaming Auvergne

#63a816
Notes

Beaming Auvergne (#63A816) is a true lime with a jewel character. It carries the deep, saturated richness of a gemstone. Authoritative and slightly formal, it works well for type and heavy UI elements. Its HSL profile (88°, 77%, 37%) places it in the highly saturated band at a mid lightness. Best used in small doses, like logos, CTAs, focus rings, or highlight text, where its saturation becomes a feature rather than noise. 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

Beaming
adjective

The progressive participle of beam, to emit a directional light — used as a color word since the nineteenth century for hues that read as if focused and projecting. Beaming yellow, beaming pink: the implication is luminance combined with directionality. Sits at the bright-bucket center alongside radiant and glowing.

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.
