Mapped Alcove Lagoon

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.

Arabic al-qubba, the-vault. As a color modifier, alcove implies a recessed-bedroom-or-sitting-area quality, the visual register of English-and-French-Country-House-alcove hand-built recessed-and-vaulted bedroom-or-sitting-area-recess-and-window-seat architectural surfaces under English-and-French-Country-House alcove-recess light. Sits at the modifier-and-architecture end of the grid, parallel to niche and atrium 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.
