Bastioned Hong

#900141
Notes

Bastioned Hong (#900141) 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 (333°, 99%, 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 teal. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Bastioned
adjective

Italian bastionato, fortified-with-bastions — past-participle of bastion, derived from bastia (fortified-tower). As a color modifier, bastioned implies a saturated-and-fortified-and-projecting quality, the deep-rich color of Vauban-period military-fortress star-fort projecting-bastion stone-architecture. Sits at the bold-and-fortified end of the grid, parallel to fortified and buttressed.

Hong
noun

The fundamental Chinese word for red — and the cultural color of weddings, festivals, lacquerware, and prosperity across thousands of years of Han through modern use. The color refers to zhongguohong (China red) — the saturated lacquer red of imperial palaces and bridal sashes: a saturated, slightly orange-shifted deep red with the high gloss of lacquer. Brighter than crimson, deeper than vermillion.
