Lined Pall Lagoon

#1eb9d8
Notes

Lined Pall Lagoon (#1EB9D8) 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 (190°, 76%, 48%) places it in the highly saturated band at a mid lightness. Best used in small doses, like logos, CTAs, focus rings, or highlight text, where its saturation becomes a feature rather than noise. 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.

Pall
modifier

Latin pallium, cloak-or-funeral-cover. As a color modifier, pall implies a cloaked-and-shrouded-and-funereal quality, the visual register of Roman-Catholic-and-Anglican-pall hand-cloaked-and-shrouded-and-funereal Roman-Catholic-and-Anglican-and-Orthodox-funeral funeral-pall-and-coffin-shroud-and-altar-cloth surfaces under Roman-Catholic-and-Anglican funeral-pall-and-coffin-shroud cathedral-incense light. Sits at the modifier-and-mood end of the grid, parallel to gloom and shade 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.
