Lucid Flurry Lagoon

#0b71a8
Notes

Lucid Flurry Lagoon (#0B71A8) is a true azure with a jewel character. It carries the deep, saturated richness of a gemstone. Authoritative and slightly formal, it works well for type and heavy UI elements. Its HSL profile (201°, 88%, 35%) 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 orange. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Lucid
adjective

Latin lūcidus, clear / bright — derived from lūx (light). As a color modifier, lucid implies a clear-and-readable quality where the hue is unambiguous and free of optical clutter. Sits at the crisp-and-clear end of the grid, parallel to pellucid and plain in usage.

Flurry
modifier

Imitative origin, quick-burst-of-snow. As a color modifier, flurry implies a quick-burst-of-snow-and-light-and-fluttering quality, the visual register of Adirondack-and-Vermont-flurry hand-quick-burst-of-snow-and-light-and-fluttering Adirondack-and-Vermont-flurry-and-New-England-snow flurry-and-quick-burst-of-snow surfaces under Adirondack-and-Vermont-flurry-and-New-England-snow Adirondack-and-Green-Mountains-and-White-Mountains New-England-snow-light. Sits at the modifier-and-weather end of the grid, parallel to slush and thaw 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.
