Cool Void Lagoon

Old English cōl, of low temperature — used as a color modifier as the complement to warm. Cool gray, cool blue: the optical impression of a slight blue-green shift, even within otherwise warm or neutral hues. Sits across the crisp, hushed, pale, and neutral buckets.

Latin vocivus, empty-or-vacant. As a color modifier, void implies an empty-and-vacant-and-bottomless quality, the visual register of Yves-Klein-and-Rothko-void hand-empty-and-vacant-and-bottomless Yves-Klein-and-Rothko-and-Malevich-Black-Square voided-and-empty-and-vacant-and-bottomless surfaces under Yves-Klein-and-Rothko-and-Malevich-Black-Square monochrome-canvas-and-color-field-and-suprematist gallery-and-void-light. Sits at the modifier-and-mood end of the grid, parallel to blank and hollow 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.
