Clean Awe Lagoon

#09b0d3
Notes

Clean Awe Lagoon (#09B0D3) 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 (190°, 92%, 43%) 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

Clean
adjective

Old English clǣne, pure, free of dirt — used as a color modifier since the medieval period for hues that read as crisp and uncontaminated by other pigments. Clean white, clean blue: moderate saturation combined with optical clarity. Sits at the crisp-bucket center alongside clear and true.

Awe
modifier

Old Norse agi, fright-and-reverence. As a color modifier, awe implies a reverent-and-overwhelmed-and-hushed quality, the visual register of Burkean-sublime-and-Caspar-David-Friedrich-awe hand-reverent-and-overwhelmed-and-hushed Burkean-sublime-and-Caspar-David-Friedrich-and-Romantic-vista awed-and-reverent-and-overwhelmed-and-hushed surfaces under Burkean-sublime-and-Caspar-David-Friedrich-and-Romantic-vista alpine-and-storm-cloud-and-mountain-pass cathedral-of-nature-light. Sits at the modifier-and-mood end of the grid, parallel to bliss and grace 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.
