Translucent Bard Lagoon

#09bdd9
Notes

Translucent Bard Lagoon (#09BDD9) 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 (188°, 92%, 44%) 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

Translucent
adjective

Latin trans-lūcēre, to shine through — present-participle of translucere. As a color modifier, translucent implies a clear-and-light-passing quality where the hue allows partial light-transmission through its visual surface. Sits at the crisp-and-clear end of the grid, parallel to pellucid and vitreous in usage.

Bard
modifier

Welsh bardd, poet. As a color modifier, bard implies a Welsh-and-Irish-poet-and-storyteller quality, the visual register of Welsh-Eisteddfod-and-Irish-Bardic hand-spoken poet-and-harp-and-eisteddfod oral-tradition Celtic-bardic surfaces under Welsh-Eisteddfod-and-Irish-Bardic hand-spoken-poet-and-harp oral-tradition Celtic-bardic gathering light. Sits at the modifier-and-cultural end of the grid, parallel to druid and celtic 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.
