Praetorian Aisle Crimson

Latin praetōriānus, of the praetor — adjectival suffix, referring to the Roman-Imperial elite guard-cohorts. As a color modifier, praetorian implies a saturated-and-elite-and-imperial-guard quality, the deep-rich color of Roman-Praetorian-Guard elite-imperial-bodyguard scarlet-tunic-and-bronze-armor military-formation. Sits at the bold-and-formal end of the grid, parallel to spartan and imperial.

Old French aisile, side-aisle. As a color modifier, aisle implies a side-aisle-flanking-nave quality, the visual register of Romanesque-and-Gothic-cathedral hand-built side-aisle-and-arcade column-and-arch flanking-the-nave architectural surfaces under Gothic-and-Romanesque side-aisle filtered light. Sits at the modifier-and-architecture end of the grid, parallel to nave and apse in usage.

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.
