Gladiatorial Jiang

#910a0b
Notes

Gladiatorial Jiang (#910A0B) 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 (360°, 87%, 30%) 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

Gladiatorial
adjective

Latin gladiātōrius, of the gladiator — adjectival suffix, derived from gladius (short-sword). As a color modifier, gladiatorial implies a saturated-and-combative-and-bloody quality, the deep-rich color of Roman-Colosseum gladiator-arena bloody-tunic-and-shield combat-attire. Sits at the bold-and-formal end of the grid, parallel to spartan and valiant.

Jiang
noun

A deep crimson historical Chinese color — used in the jiangcao (deep-crimson) silks of Tang-dynasty court robes and the lacquer of Han-period burial chambers. The color refers to a jiang-dyed silk in the Forbidden City collection: a deep, slightly cool dark red with the matte finish of multi-bath dyeing. Deeper than hong, cooler than karakurenai.

Moderately saturated colors gain a small bump in P3 — the difference is usually visible side-by-side on wide-gamut hardware but won't change the character of the color.
