Honest Stole Lagoon

#01a9c4
Notes

Honest Stole Lagoon (#01A9C4) 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 (188°, 99%, 39%) 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

Honest
adjective

Latin honestus, honorable — used as a color modifier since the seventeenth century for hues that read as straightforward and unembellished, the working browns and grays of vernacular architecture rather than the polished shades of court fashion. Honest brown, honest gray: moderate saturation combined with optical directness. Sits at the crisp-bucket alongside plain and frank.

Stole
modifier

Latin stola, Roman-women's-and-priestly-robe. As a color modifier, stole implies a Roman-women's-and-priestly-robe quality, the visual register of Roman-stola-and-Catholic-priestly-stole hand-Roman-women's-and-priestly-robe Roman-stola-and-Catholic-priestly-stole-and-Anglican-tippet stole-and-Roman-women's-and-priestly-robe surfaces under Roman-stola-and-Catholic-priestly-stole-and-Anglican-tippet Republican-Rome-and-Catholic-Mass-and-Anglican-Vespers Roman-and-Mass-light. Sits at the modifier-and-textile end of the grid, parallel to cope and robe 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.
