Gladiatorial Saint Sapphire

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.

Latin sanctus, holy. As a color modifier, saint implies a hagiographic-and-relic quality, the visual register of Greek-Orthodox-and-Roman-Catholic-Saint hand-painted icon-and-relic-and-halo-and-iconostasis hagiographic surfaces under Greek-Orthodox-and-Roman-Catholic hand-painted icon-and-iconostasis hagiographic-tradition candlelight. Sits at the modifier-and-cultural end of the grid, parallel to monk and friar in usage.

An iron-and-titanium-bearing corundum — the same mineral as ruby, hardness 9 on the Mohs scale, mined for two millennia from Sri Lanka, Burma, Madagascar, and the Cashmere mines of British India. The color refers to a fine Kashmir-cut sapphire: a saturated, slightly violet-shifted deep blue with the gem's signature internal velvet — a quality of light scattering in the stone that faceted glass cannot replicate. Cooler than cobalt, deeper than azure.
