Lined Eden Ocean

#128392
Notes

Lined Eden Ocean (#128392) is a deep cyan with a jewel character. It carries the deep, saturated richness of a gemstone. Authoritative and slightly formal, it works well for type and heavy UI elements. Its HSL profile (187°, 78%, 32%) places it in the highly saturated band at a dark 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.

Eden
modifier

Hebrew ‘Ēden, garden-of-paradise. As a color modifier, eden implies a primal-paradise-and-garden-of-creation quality, the visual register of Genesis-Eden-and-Lucas-Cranach-paradise hand-primal-paradise-and-garden-of-creation Genesis-Eden-and-Lucas-Cranach-paradise-and-Northern-Renaissance eden-and-primal-paradise-and-garden-of-creation surfaces under Genesis-Eden-and-Lucas-Cranach-paradise-and-Northern-Renaissance Cranach-and-Bosch-and-Hieronymus primal-garden-light.

Ocean
noun

The body of saltwater that covers seventy percent of Earth's surface — a single connected mass divided by convention into Atlantic, Pacific, Indian, Southern, and Arctic.

Deeper than mediterranean, cooler than peacock.
