Buttressed Savory Crimson

#a71a1c
Notes

Buttressed Savory Crimson (#A71A1C) is a true red 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 (359°, 73%, 38%) 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 cyan. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Buttressed

Savory
modifier

Latin satureia, peppery-Mediterranean-herb. As a color modifier, savory implies a peppery-Mediterranean-herb-and-Provençal-bouquet quality, the visual register of Provençal-bouquet-garni-and-summer-savory hand-peppery-Mediterranean-herb-and-Provençal-bouquet Provençal-bouquet-garni-and-summer-savory-and-herbes-de-Provence savory-and-peppery-Mediterranean-herb surfaces under Provençal-bouquet-garni-and-summer-savory-and-herbes-de-Provence Provençal-and-Tuscan-and-Catalan herb-garden-light.

Crimson
noun

From the Old Spanish cremesin, itself from the Arabic qirmiz — the kermes scale insect, dried and ground into a brilliant carmine dye prized in the medieval Mediterranean. For centuries the most expensive red on a draper's shelf, reserved for cardinals, kings, and the cloth that gave English the word crimson. Cooler than scarlet, deeper than rose; the color of pomegranate seeds and a serious occasion.
