Buttressed Savory Ruby

#a2221d
Notes

Buttressed Savory Ruby (#A2221D) 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 (2°, 70%, 37%) 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
adjective

Old French bouterez, thrusting-mass — past-participle of buttress, derived from bouter (to thrust). As a color modifier, buttressed implies a saturated-and-architecturally-supported quality, the deep-rich color of Gothic-Cathedral flying-buttress-and-rib-vault stone-architecture. Sits at the bold-and-fortified end of the grid, parallel to fortified and reinforced.

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. Sits at the modifier-and-flavor end of the grid, parallel to hyssop and lovage in usage.

Ruby
noun

From the Latin ruber — simply, red. The gemstone is a chromium-tinged corundum, harder than anything in nature except diamond, and so saturated that a fine Burmese pigeon's blood ruby at auction outpaces a comparable diamond by weight. The color borrows the gem's confidence: a clear, glassy red without the brown of garnet or the blue of crimson.

Moderately saturated colors gain a small bump in P3 — the difference is usually visible side-by-side on wide-gamut hardware but won't change the character of the color.
