Stalwart Auvergne

#31990a
Notes

Stalwart Auvergne (#31990A) is a deep green 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 (104°, 88%, 32%) places it in the highly saturated band at a dark 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 violet. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Stalwart
adjective

Old English stǣl-wyrðe, stable-and-worthy. As a color modifier, stalwart implies a saturated-and-loyal-and-firm quality where the hue carries the dependable-and-trustworthy visual presence of a Knight-Templar guard. Sits at the bold-and-firm end of the grid, parallel to steadfast and firm 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.

Display P3 representation

The CSS Color 4 wide-gamut form of this color. Both swatches render the same color on every display — the P3 form only diverges from sRGB when a designer pushes channels outside sRGB's reach.

This color is chromatic enough that authoring it as P3 native (instead of clamping to sRGB) gives a perceptibly more saturated render on wide-gamut displays — modern Macs, iPhones, iPads, and most recent OLED laptops.
