Plain Pelt 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 French pellete, small-skin. As a color modifier, pelt implies a fur-with-skin-and-hide quality, the visual register of fur-trapper-and-Hudson-Bay-Pelt hand-trapped-and-skinned beaver-and-otter-and-mink hand-trapped-fur-pelt-and-hide surfaces under Hudson-Bay-and-fur-trapper hand-trapped pelt-and-hide trading-post light. Sits at the modifier-and-texture end of the grid, parallel to hide and fur 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.
