Lined Bark Lagoon

#30c1e2
Notes

Lined Bark Lagoon (#30C1E2) 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°, 75%, 54%) 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.

Bark
modifier

Old Norse bǫrkr, bark. As a color modifier, bark implies a tree-bark-and-rough-and-cork quality, the visual register of birch-and-oak-and-cork-bark hand-stripped-and-cork-bark birch-and-oak-and-cork-tree-bark hand-stripped-tree-bark surfaces under birch-and-oak-and-cork-bark hand-stripped-bark forest light. Sits at the modifier-and-texture end of the grid, parallel to rough and cane 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.
