Buttressed Beaujolais

#a80431
Notes

Buttressed Beaujolais (#A80431) is a deep 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 (344°, 95%, 34%) 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 teal. 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.

Beaujolais
noun

The French wine region just south of Burgundy — and the Gamay-based reds of Beaujolais Nouveau. The color refers to a fresh Beaujolais Nouveau in a glass: a saturated, slightly cool red with the optical brightness of low-tannin young wine. Lighter than Burgundy, brighter than Chianti.
