Sterile Rise Lagoon

Latin sterilis, barren / not-fertile — sharing root with Greek steiros (barren). As a color modifier, sterile implies a clear-and-medical-clean-and-stripped quality, the crisp color of operating-theater surgical-environment white-and-stainless-steel surfaces. Sits at the crisp-and-clean end of the grid, parallel to sanitary and hygienic in usage.

Old English rīsan, to ascend. As a color modifier, rise implies an ascending-and-emerging quality, the visual register of moonrise-and-sunrise ascending-and-emerging horizon-and-celestial-body atmospheric scattering-of-light surfaces under ascending horizon-and-celestial light. Sits at the modifier-and-time end of the grid, parallel to set and sunup 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.
