Clear Icicle Lagoon

From the Latin clarus, bright, distinct — used as a color modifier since the medieval period for hues without haze or mixing. Clear blue sky, clear green water: the implication is moderate saturation combined with optical clarity. Sits at the crisp-bucket center alongside clean and true.

Old English īsgicel, ice-and-icicle. As a color modifier, icicle implies a hanging-ice-and-eaves-frozen-drip quality, the visual register of Alpine-eaves-and-Norwegian-stave-icicle hand-hanging-ice-and-eaves-frozen-drip Alpine-eaves-and-Norwegian-stave-icicle-and-Cairngorm-ledge icicle-and-hanging-ice-and-eaves-frozen-drip surfaces under Alpine-eaves-and-Norwegian-stave-icicle-and-Cairngorm-ledge Alpine-Dolomites-and-Norwegian-stave-church frozen-drip-light. Sits at the modifier-and-weather end of the grid, parallel to floe and berg 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.
