Mapped Roman Ocean

Latin mappa, cloth / napkin — past-participle of map. As a color modifier, mapped implies a clear-and-cartographic-and-surveyed quality, the crisp color of Ordnance-Survey-and-USGS scientific-and-cadastral cartographic-and-topographic mapping-and-projection. Sits at the crisp-and-mapped end of the grid, parallel to plotted and surveyed in usage.

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.

The body of saltwater that covers seventy percent of Earth's surface — a single connected mass divided by convention into Atlantic, Pacific, Indian, Southern, and Arctic. The color refers to the average reflectance of mid-depth temperate ocean: a saturated, slightly green-shifted deep blue with the optical depth of a body of water that absorbs all light below the photic zone. Deeper than mediterranean, cooler than peacock.
