Senatorial Caftan

#a71781
Notes

Senatorial Caftan (#A71781) 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 (316°, 76%, 37%) places it in the highly saturated band at a mid 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

Senatorial
adjective

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.

Caftan
noun

Persian قفطان, kaftan — a long, loose-fitting Middle-Eastern and North-African robe of layered silk-and-velvet, often dyed in deep-magenta fuchsine or natural kermes for ceremonial occasions. Caftan color refers to an Ottoman-period 19th-century caftan in the Topkapi Palace harem-wing collection: a saturated, slightly cool deep magenta with the velvet finish of multi-bath natural-and-synthetic dye on jacquard-figured silk.
