Calm Anise Lagoon

#10bdde
Notes

Calm Anise Lagoon (#10BDDE) is a true cyan with a neon character. It sits at the high-saturation edge of its family. Use it sparingly, as signage, accent, or highlight against darker surfaces. Its HSL profile (190°, 87%, 47%) 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

Calm
adjective

Latin calma, heat of the day — paradoxically drifted in Italian to mean stillness. Used as a color modifier since the seventeenth century for hues that read as untroubled. Calm blue, calm gray: moderate saturation combined with optical quiet. Sits at the crisp-bucket near quiet and steady.

Anise
modifier

Latin anīsum, sweet-licorice-seed. As a color modifier, anise implies a sweet-licorice-and-Mediterranean-aniseed quality, the visual register of Sicilian-and-Provençal-anise hand-sweet-licorice-and-Mediterranean-aniseed Sicilian-and-Provençal-anise-and-Pernod-Ricard anise-and-sweet-licorice surfaces under Sicilian-and-Provençal-anise-and-Pernod-Ricard Marseille-and-Sicily-and-Pastis Mediterranean-licorice-light. Sits at the modifier-and-flavor end of the grid, parallel to clove and caraway 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.
