Tucked Quad Lagoon

Old English tūcian, to torment / pull — past-participle of tuck. As a color modifier, tucked implies a clear-and-fitted-and-arranged quality where the hue carries the visual register of carefully-tucked-and-neatly-fitted shirt-into-trouser dress-attire. Sits at the crisp-and-finished end of the grid, parallel to trim and pressed in usage.

Latin quadrum, square. As a color modifier, quad implies an Oxford-and-Cambridge-college-quadrangle quality, the visual register of Oxford-and-Cambridge-college-quad hand-built four-sided-college-courtyard quad-and-cloister-and-lawn architectural surfaces under Oxford-and-Cambridge college-quadrangle academic light. Sits at the modifier-and-architecture end of the grid, parallel to court 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.
