Inscribed Reach Lagoon

Latin īnscrībere, to write upon — past-participle of inscribe. As a color modifier, inscribed implies a clear-and-text-or-pattern-cut quality, the crisp color of Roman-Imperial-period monumental-stone inscription-and-monumental-text incised-relief. Sits at the crisp-and-incised end of the grid, parallel to etched and engraved in usage.

Old English ræcan, to extend. As a color modifier, reach implies a tidal-river-stretch quality, the visual register of Thames-Reach-and-Severn-Reach mid-river deep-water tidal-stretch-and-mudflat working-river surfaces under London-Thames-and-Severn-Estuary tidal-river overcast working light. Sits at the modifier-and-place end of the grid, parallel to strand and bank in usage.

A shallow body of saltwater partially or fully enclosed by a barrier — coral atoll lagoons in the Pacific, Venice's Laguna Veneta, the Florida Keys' backcountry. The color refers to the average reflectance of a calm tropical lagoon at midday: a saturated, slightly muted blue-green with the optical clarity of shallow water over white sand. Brighter than reef, cooler than aquamarine, with the postcard weight of a Pacific atoll seen from above.
