Praetorian Marakat

#378b01
Notes

Praetorian Marakat (#378B01) 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 (97°, 99%, 27%) 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 indigo. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Praetorian
adjective

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.

Marakat
noun

The Sanskrit word for emerald — used in Vedic and Mughal jewelry vocabulary for the saturated deep green of fine emeralds. Marakat gave the Greek smaragdus and ultimately English emerald. The color refers to a faceted Mughal-period Colombian emerald: a saturated, slightly cool deep green with the gem's signature internal life.
