Clean Druid Lagoon

Old English clǣne, pure, free of dirt — used as a color modifier since the medieval period for hues that read as crisp and uncontaminated by other pigments. Clean white, clean blue: moderate saturation combined with optical clarity. Sits at the crisp-bucket center alongside clear and true.

Latin Druidae, Druids. As a color modifier, druid implies a Celtic-priest-and-mistletoe quality, the visual register of Celtic-British-and-Gaulish-Druidic Druidic hand-cut sacred-grove-and-mistletoe-and-stone-circle pre-Christian-Celtic surfaces under Celtic-British-and-Gaulish Druidic sacred-grove-and-stone-circle dawn light. Sits at the modifier-and-cultural end of the grid, parallel to celtic and gaul 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.
