Quiet Sol Lagoon

#235d71
Notes

Quiet Sol Lagoon (#235D71) is a deep 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 (195°, 53%, 29%) places it in the balanced band at a dark lightness. It works well as a headline, icon, or deep background in an otherwise light layout, pairing cleanly with cream, bone, and warm neutrals. For a confident two-color system, pair it with its complementary orange. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Quiet
adjective

Latin quietus, at rest — used as a color modifier since the medieval period for hues that read as restrained. Quiet pink, quiet blue: low saturation combined with optical calmness. Sits across the crisp and hushed buckets where the color is present but doesn't ask for attention.

Sol
modifier

Latin sol, sun-and-Roman-sun-god. As a color modifier, sol implies a Roman-sun-god-and-stellar-disc quality, the visual register of Roman-Sol-Invictus-and-Apollo-sun hand-Roman-sun-god-and-stellar-disc Roman-Sol-Invictus-and-Apollo-sun-and-Helios-chariot sol-and-Roman-sun-god-and-stellar-disc surfaces under Roman-Sol-Invictus-and-Apollo-sun-and-Helios-chariot December-25-and-Helios-and-quadriga noon-stellar-disc-light. Sits at the modifier-and-zodiac end of the grid, parallel to luna and terra 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.
