Stable Pimento Lagoon

#03b1ce
Notes

Stable Pimento Lagoon (#03B1CE) is a true cyan with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (189°, 97%, 41%) places it in the highly saturated band at a mid lightness. Best used in small doses, like logos, CTAs, focus rings, or highlight text, where its saturation becomes a feature rather than noise. 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

Stable
adjective

Latin stabilis, standing-firm — sharing root with stand.

Sits at the crisp-and-firm end of the grid, parallel to steady and settled in usage.

Pimento
modifier

Spanish pimiento, sweet-red-Iberian-capsicum. As a color modifier, pimento implies a sweet-red-Iberian-capsicum-and-allspice-berry quality, the visual register of Spanish-and-Jamaican-pimento hand-sweet-red-Iberian-capsicum-and-allspice-berry Spanish-and-Jamaican-pimento-and-allspice-berry pimento-and-sweet-red-Iberian-capsicum surfaces under Spanish-and-Jamaican-pimento-and-allspice-berry Iberian-and-Jamaican-Blue-Mountain Iberian-and-Jamaican-spice-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.
