Cleansed Atlas Lagoon

#419ba3
Notes

Cleansed Atlas Lagoon (#419BA3) 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 (185°, 43%, 45%) 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

Cleansed
adjective

Old English clǣnsian, to make clean — past-participle of cleanse. As a color modifier, cleansed implies a clear-and-purified quality where the hue has been stripped of any contaminating tint. Sits at the crisp-and-clear end of the grid, parallel to fresh and pristine in usage.

Atlas
modifier

Greek Ἄτλας, Titan-bearing-the-heavens. As a color modifier, atlas implies a Titan-bearing-heaven-and-globe-bearer quality, the visual register of Farnese-Atlas-and-Titanomachy-Atlas hand-Titan-bearing-heaven-and-globe-bearer Farnese-Atlas-and-Titanomachy-Atlas-and-Hellenistic-marble atlas-and-Titan-bearing-heaven surfaces under Farnese-Atlas-and-Titanomachy-Atlas-and-Hellenistic-marble Naples-museum-and-celestial-globe globe-bearer-light. Sits at the modifier-and-myth end of the grid, parallel to titan and zeus 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.
