Etched Eden Lagoon

#406c7a
Notes

Etched Eden Lagoon (#406C7A) is a true cyan with an earthy character. It leans grounded and natural, the kind of color that plays well with wood, clay, linen, and warm neutrals. Its HSL profile (194°, 31%, 36%) 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

Etched
adjective

German ätzen, to etch — past-participle of etch. As a color modifier, etched implies a clear-and-precisely-incised quality, the crisp color of Rembrandt-and-Dürer hand-pulled etching-print fine-line incised-image. Sits at the crisp-and-incised end of the grid, parallel to engraved and inscribed 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.

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.
