Gladiatorial Rush

#5b8517
Notes

Gladiatorial Rush (#5B8517) is a deep lime 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 (83°, 71%, 31%) places it in the balanced band at a dark lightness. It works well as a headline, icon, or deep background in an otherwise light layout, pairing cleanly with cream, bone, and warm neutrals. For a confident two-color system, pair it with its complementary indigo. 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.

Rush
noun

The genus Juncus — wetland sedge-family plants whose hollow green stems were used historically for rushlights (torches dipped in tallow) and traditional weaving. The color refers to a clump of fresh rushes in a damp meadow: a saturated, slightly cool deep yellow-green with the matte finish of round hollow stalks.

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.
