Wholesome Flash Lagoon

#2aacc5
Notes

Wholesome Flash Lagoon (#2AACC5) 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°, 65%, 47%) 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

Wholesome
adjective

An adjectival form of whole — used as a color modifier since the sixteenth century for hues that read as healthy and unadulterated. Wholesome cream, wholesome wheat: moderate saturation combined with the optical impression of a natural origin. Sits at the crisp-bucket alongside genuine.

Flash
modifier

Middle English flasshen, to-splash-or-burst. As a color modifier, flash implies a sudden-and-bursting-and-bright quality, the visual register of lightning-strike-and-camera-flash hand-sudden-and-bursting-and-bright lightning-strike-and-camera-flash-and-magnesium-powder flashed-and-sudden-and-bursting surfaces under lightning-strike-and-camera-flash-and-magnesium-powder split-second-burst storm-cloud-and-studio-light. Sits at the modifier-and-mood end of the grid, parallel to spark and blaze 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.
