Gladiatorial Corsica

#178e38
Notes

Gladiatorial Corsica (#178E38) is a deep green 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 (137°, 72%, 32%) 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 magenta. 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.

Corsica
noun

The French Mediterranean island — and the saturated blue-green of Corsican calanques (rocky coves) at Calanche de Piana and Bonifacio. Corsica refers to a Bonifacio cove at midday: a saturated, slightly cool deep blue-green with the optical clarity of cold Tyrrhenian Sea water.
