Plain Eave Lagoon

Latin planus, flat, level — used as a color modifier since the medieval period for hues that read as undecorated and direct. Plain white, plain blue: moderate saturation, no shift, no surface effect. Sits in the crisp-bucket center, with the implication of restraint rather than absence.

Old English efes, roof-edge. As a color modifier, eave implies a roof-overhang-and-edge quality, the visual register of Japanese-engawa-and-English-eave hand-built roof-overhang-and-edge eave-and-fascia-and-soffit architectural surfaces under Japanese-and-English eave-edge filtered light. Sits at the modifier-and-architecture end of the grid, parallel to gable and frieze 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.
