Praetorian Atlantic
Praetorian Atlantic (#075BA1) is a deep azure 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 (207°, 92%, 33%) 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 orange. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
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.
The body of saltwater between the Americas and Eurasia/Africa — second-largest of Earth's oceans by area, deeper colored by river silt than the Mediterranean. The color refers to the average reflectance of mid-North Atlantic water on a clear day: a saturated, slightly muted blue with the optical depth of cold open water. Deeper than mediterranean, cooler than peacock, with the geographic weight of an ocean named for Atlas at its western horizon.
