Opulent Annatto

#a4250a
Notes

Opulent Annatto (#A4250A) 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 (11°, 89%, 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 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.

Annatto
noun

Bixa orellana, the tropical shrub whose seeds yield a red-orange dye used as food coloring (in cheese, butter, and margarine) and as body paint by the Caribbean and Central American indigenous peoples. The color refers to fresh annatto paste: a saturated, slightly orange red with the matte finish of plant-derived pigment. Warmer than vermillion, drier than tomato.
