Calm Flare Lagoon

Latin calma, heat of the day — paradoxically drifted in Italian to mean stillness. Used as a color modifier since the seventeenth century for hues that read as untroubled. Calm blue, calm gray: moderate saturation combined with optical quiet. Sits at the crisp-bucket near quiet and steady.

Origin obscure, attested c. 1540, to-burn-with-an-unsteady-flame. As a color modifier, flare implies a sudden-and-spreading-and-bright-burst quality, the visual register of signal-flare-and-solar-flare hand-sudden-and-spreading-and-bright-burst signal-flare-and-solar-flare-and-magnesium-distress flared-and-sudden-and-spreading-and-bright surfaces under signal-flare-and-solar-flare-and-magnesium-distress shipboard-and-rescue-and-corona high-intensity-light. Sits at the modifier-and-mood end of the grid, parallel to blaze and flash 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.
