Lined Diana Lagoon

#2cb5d3
Notes

Lined Diana Lagoon (#2CB5D3) is a true cyan with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (191°, 65%, 50%) places it in the balanced band at a mid lightness. It works across type, buttons, and borders, saturated enough to feel deliberate but balanced enough to not fight the rest of the palette. For a confident two-color system, pair it with its complementary red. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Lined
adjective

Old English līne, line / cord — past-participle of line. As a color modifier, lined implies a clear-and-coordinated-and-supported quality where the hue carries the visual register of carefully-lined-and-supported textile-or-print surface. Sits at the crisp-and-finished end of the grid, parallel to trim and coordinated in usage.

Diana
modifier

Latin Diana, Roman-goddess-of-moon-and-hunt. As a color modifier, diana implies a Roman-goddess-and-moon-and-hunter-and-virgin quality, the visual register of Roman-Diana-and-Ephesian-Artemis hand-Roman-goddess-and-moon-and-hunter-and-virgin Roman-Diana-and-Ephesian-Artemis-and-Lake-Nemi diana-and-Roman-goddess-and-moon-and-hunter surfaces under Roman-Diana-and-Ephesian-Artemis-and-Lake-Nemi Aventine-Hill-and-Nemi-grove moonlit-grove-light. Sits at the modifier-and-myth end of the grid, parallel to luna and hera in usage.

Lagoon
noun

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.
