Sumptuous Pelargonium

#831b73
Notes

Sumptuous Pelargonium (#831B73) 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 (309°, 66%, 31%) places it in the balanced band at a dark lightness. It works well as a headline, icon, or deep background in an otherwise light layout, pairing cleanly with cream, bone, and warm neutrals. 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.

Pelargonium
noun

South African Pelargonium genus — particularly the P. × hortorum and P. peltatum (zonal and ivy-leaved geraniums), cultivated worldwide for their deep-magenta-to-scarlet umbels. Pelargonium color refers to a fully bloomed P. × hortorum terminal umbel on a Mediterranean balcony: a saturated, slightly cool deep magenta with the velvet finish of fresh five-petaled flowers in dense radiating clusters. Greek pelargós (stork).
