Earnest Roman Sapphire

Old English eornost, seriousness, zeal. Used as a color modifier since the nineteenth century for hues that read as committed but unshowy — the working blues of denim, the deep greens of Quaker meetinghouses. Sits in the bold-and-quiet corner of the grid, slightly less luminous than resolute and slightly less institutional than imperial.

Latin Romanus, of-Rome. As a color modifier, roman implies an empire-built-and-classical quality, the visual register of Roman-Imperial hand-laid pavement-and-fresco-and-bronze-and-marble Republican-Imperial classical surfaces under Mediterranean-Roman-Imperial classical-architecture afternoon light. Sits at the modifier-and-cultural end of the grid, parallel to etruscan and hellenic 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.
