Pellucid Berg Lagoon

#28bcdd
Notes

Pellucid Berg Lagoon (#28BCDD) 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 (191°, 73%, 51%) 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

Pellucid
adjective

Latin pellūcidus, transparent — derived from per-lūcēre (to shine through). As a color modifier, pellucid implies a clear-and-translucent quality where the hue reads with optical clarity and minimal turbidity. Sits at the crisp-and-clear end of the grid, parallel to lucid and translucent in usage.

Berg
modifier

Norwegian isberg, mountain-of-ice. As a color modifier, berg implies an iceberg-and-Antarctic-tabular-ice quality, the visual register of Antarctic-and-Greenland-iceberg hand-iceberg-and-Antarctic-tabular-ice Antarctic-and-Greenland-iceberg-and-Larsen-Ice-Shelf berg-and-iceberg-and-Antarctic-tabular-ice surfaces under Antarctic-and-Greenland-iceberg-and-Larsen-Ice-Shelf Ross-Sea-and-Weddell-Sea-and-Disko-Bay tabular-iceberg-light. Sits at the modifier-and-weather end of the grid, parallel to floe and icicle 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.
