Praetorian Scot Ruby

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 English Scotti, of-Scotland. As a color modifier, scot implies a Highland-and-tartan quality, the visual register of Scottish-Highland-and-Lowland hand-woven tartan-and-wool-and-tweed peat-and-heather-and-stone surfaces under Scottish-Highland-and-Lowland tartan-and-tweed Highland-pasture light. Sits at the modifier-and-cultural end of the grid, parallel to welsh and irish in usage.

From the Latin ruber — simply, red. The gemstone is a chromium-tinged corundum, harder than anything in nature except diamond, and so saturated that a fine Burmese pigeon's blood ruby at auction outpaces a comparable diamond by weight. The color borrows the gem's confidence: a clear, glassy red without the brown of garnet or the blue of crimson.
