Buttressed Malbec

#a63a56
Notes

Buttressed Malbec (#A63A56) is a true red with an earthy character. It leans grounded and natural, the kind of color that plays well with wood, clay, linen, and warm neutrals. Its HSL profile (344°, 48%, 44%) 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 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.

Malbec
noun

A red-wine grape originally from Cahors in southwest France, now most associated with Argentine Mendoza wine regions. The color refers to a young Argentine Malbec: a deep, slightly cool dark red with the high tannin opacity of high-altitude grape wine. Deeper than Tempranillo, cooler than Rioja.
