Bastioned Hide Crimson

#991404
Notes

Bastioned Hide Crimson (#991404) is a deep red 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 (6°, 95%, 31%) 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 cyan. 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.

Hide
modifier

Old English hȳd, skin / hide. As a color modifier, hide implies a tanned-leather-and-skin quality, the visual register of cattle-and-deer-and-pig-hide hand-tanned-and-vegetable-tanned cattle-and-deer-and-pig-skin hand-tanned-leather-hide surfaces under tanned-leather-and-skin tanning-yard light. Sits at the modifier-and-texture end of the grid, parallel to pelt and fur in usage.

Crimson
noun

From the Old Spanish cremesin, itself from the Arabic qirmiz — the kermes scale insect, dried and ground into a brilliant carmine dye prized in the medieval Mediterranean. For centuries the most expensive red on a draper's shelf, reserved for cardinals, kings, and the cloth that gave English the word crimson. Cooler than scarlet, deeper than rose; the color of pomegranate seeds and a serious occasion.
