Plainspoken Spun Lagoon

#338b9f
Notes

Plainspoken Spun Lagoon (#338B9F) 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 (191°, 51%, 41%) 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

Plainspoken
adjective

English compound plain + spoken — past-participle of speak. As a color modifier, plainspoken implies a clear-and-direct-and-straightforward quality where the hue carries the visual register of unembellished-honest declaration. Sits at the crisp-and-honest end of the grid, parallel to candid and direct in usage.

Spun
modifier

Old English spinnan, to-spin. As a color modifier, spun implies a hand-spun-fiber quality, the visual register of hand-spinning-wheel hand-spun-and-twisted wool-and-flax-and-cotton hand-spun-fiber-on-spinning-wheel surfaces under hand-spun-and-twisted spinning-wheel working light. Sits at the modifier-and-texture end of the grid, parallel to woven and knit 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.
