Opulent Feast Crimson

#aa1d21
Notes

Opulent Feast Crimson (#AA1D21) is a true red with a warm character. It leans warm, pulling light toward red, orange, and yellow. Naturally inviting, it suits editorial and hospitality contexts. Its HSL profile (358°, 71%, 39%) 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

Opulent
adjective

Latin opulentus, rich / wealthy — derived from ops (wealth). As a color modifier, opulent implies a saturated-and-luxurious quality, the deep-rich color of Belle-Époque and Gilded-Age interior-decoration silk-and-velvet textiles. Sits at the bold-and-saturated end of the grid, parallel to lavish and sumptuous.

Feast
modifier

Latin festus, festal-day. As a color modifier, feast implies a celebratory-and-feast-day quality, the visual register of Christmas-and-Easter-Feast celebratory-and-feast-day liturgical-and-secular ceremonial-and-festal-banquet surfaces under feast-day candlelit-and-ceremonial-banquet light. Sits at the modifier-and-time end of the grid, parallel to yule and easter in usage.

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.

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.
