Surveyed Hall Lagoon

Old French surveer, to look upon — past-participle of survey. As a color modifier, surveyed implies a clear-and-measured-and-coordinated quality, the crisp color of Mason-Dixon-Line-and-Royal-Navy-Hydrographic scientific-and-cadastral land-and-sea surveying tradition. Sits at the crisp-and-mapped end of the grid, parallel to mapped and plotted in usage.

Old English heall, large-room / mansion. As a color modifier, hall implies a great-room-and-banquet quality, the visual register of Hampton-Court-and-Westminster hand-built timber-roof-and-stone-pillar great-hall ceremonial-and-dining surfaces under Tudor-and-Plantagenet great-hall ceremonial-feast candlelight. Sits at the modifier-and-place end of the grid, parallel to manor and court 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.
