Senatorial Pelargonium
Senatorial Pelargonium (#A11B80) is a true 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 (315°, 71%, 37%) places it in the balanced band at a mid lightness. It works across type, buttons, and borders, saturated enough to feel deliberate but balanced enough to not fight the rest of the palette. 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
Latin senātōrius, of the senator — adjectival suffix. As a color modifier, senatorial implies a saturated-and-aristocratic-and-Roman-Republic quality, the deep-rich color of Roman-Senate toga praetexta purple-bordered ceremonial-citizen-class livery. Sits at the bold-and-aristocratic end of the grid, parallel to patrician and imperial.
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).
