Trim Glee Lagoon

Old English trymman, to make firm — sharing root with firm. As a color modifier, trim implies a clear-and-neatly-arranged quality where the hue carries the visual register of carefully-edited surface-detail. Sits at the crisp-and-neat end of the grid, parallel to neat and tidy in usage.

Old English glēo, music-or-merriment. As a color modifier, glee implies a singing-and-merry-and-bubbling quality, the visual register of Elizabethan-glee-club-and-madrigal-glee hand-singing-and-merry-and-bubbling Elizabethan-glee-club-and-madrigal-and-catch-singing gleeful-and-singing-and-merry-and-bubbling surfaces under Elizabethan-glee-club-and-madrigal-and-catch-singing parlor-and-tavern-and-court candlelit-music-light. Sits at the modifier-and-mood end of the grid, parallel to mirth and merry 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.
