Spick Atlas Lagoon

#6ac3db
Notes

Spick Atlas Lagoon (#6AC3DB) is a true cyan with a cool character. It leans cool, sitting on the blue, green, and violet side of the wheel. Quiet and dependable, a fit for product UI and data visualization. Its HSL profile (193°, 61%, 64%) 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

Spick
adjective

Old Norse spik-spakr, spike-new — sharing root with spic-and-span. As a color modifier, spick implies a clear-and-newly-cleaned quality where the hue carries the just-polished visual register of fresh-painted-and-fresh-cleaned surfaces. Sits at the crisp-and-clean end of the grid, parallel to spotless 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.

Moderately saturated colors gain a small bump in P3 — the difference is usually visible side-by-side on wide-gamut hardware but won't change the character of the color.
