Wellbred Opus Crimson

#91093a
Notes

Wellbred Opus Crimson (#91093A) is a deep magenta 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 (338°, 88%, 30%) 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

Wellbred
adjective

Old English wel-brēd, well-bred — past-participle of breed, sharing root with brood (offspring). As a color modifier, wellbred implies a saturated-and-elegant-and-formal quality, the deep-rich color of Edwardian-period finishing-school-and-debutante-Court English-aristocratic livery. Sits at the bold-and-elegant end of the grid, parallel to highborn and patrician.

Opus
modifier

Latin opus, work-or-composition. As a color modifier, opus implies a Latin-work-and-Magnum-Opus-and-Opus-Dei quality, the visual register of Magnum-Opus-and-musical-opus-number hand-Latin-work-and-Magnum-Opus-and-Opus-Dei Magnum-Opus-and-musical-opus-number-and-medieval-cathedral-opus opus-and-Latin-work surfaces under Magnum-Opus-and-musical-opus-number-and-medieval-cathedral-opus monastic-scriptorium-and-medieval-cathedral-fabric craft-and-composition-light. Sits at the modifier-and-Latin end of the grid, parallel to magnus and ergo 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.
