Authoritative Purpurnyy

#891073
Notes

Authoritative Purpurnyy (#891073) 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 (311°, 79%, 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 green. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Authoritative
adjective

Latin auctōritāt-, authority — adjectival suffix -ive. As a color modifier, authoritative implies a saturated-and-formal-imperative quality where the hue carries decisional weight and institutional credibility. Sits at the bold-and-authoritative end of the grid, parallel to commanding and magisterial in usage.

Purpurnyy
noun

Russian пурпурный, purple — derived from Latin purpura via Greek porphyra. The Russian Orthodox liturgical color for Pentecost and the deep-purple-and-gold iconostasis tradition. Purpurnyy color refers to a Russian Orthodox cathedral iconostasis royal-doors panel: a saturated, slightly cool deep violet with the matte finish of egg-tempera ultramarine-and-cinnabar on gilt gesso. Slightly cooler than Spanish púrpura.
