Sumptuous Strobilanthes

#820c73
Notes

Sumptuous Strobilanthes (#820C73) is a deep violet 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 (308°, 83%, 28%) 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

Sumptuous
adjective

Latin sūmptuōsus, expensive — derived from sūmptus (expense). As a color modifier, sumptuous implies a saturated-and-rich-and-luxurious quality, the deep-rich color of Burgundy-and-Champagne-Court late-medieval silk-and-velvet livery in the Très-Riches-Heures manuscript tradition. Sits at the bold-and-saturated end of the grid, parallel to opulent and lavish.

Strobilanthes
noun

Asian Persian shield (Strobilanthes dyerianus) — a Burmese-native evergreen shrub cultivated worldwide for its iridescent violet-and-silver leaf coloration. Strobilanthes color refers to a Strobilanthes dyerianus leaf upper surface in raking light: a saturated, slightly cool deep violet with the iridescent satin finish of structurally colored cuticular leaf surface. The genus name comes from the Greek stróbilos (cone) and anthos (flower).
