Senatorial Coiled Sapphire

Latin senātōrius, of the senator — adjectival suffix. As a color modifier, senatorial implies a saturated-and-aristocratic-and-Roman-Republic quality, the deep-rich color of Roman-Senate toga praetexta purple-bordered ceremonial-citizen-class livery. Sits at the bold-and-aristocratic end of the grid, parallel to patrician and imperial.

Old French coillir, to-collect. As a color modifier, coiled implies a wound-and-spiral quality, the visual register of hand-coiled-rope-and-clay hand-coiled-and-wound rope-and-clay-and-pottery hand-coiled-and-wound coil-and-spiral-and-pottery surfaces under hand-coiled-and-wound pottery-and-rope workshop-light. Sits at the modifier-and-texture end of the grid, parallel to twined and looped 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.
