Healthful Looped Lagoon

#3ab3d2
Notes

Healthful Looped Lagoon (#3AB3D2) is a true cyan with a cool character. It leans cool, sitting on the blue, green, and violet side of the wheel. Quiet and dependable, a fit for product UI and data visualization. Its HSL profile (192°, 63%, 53%) 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

Healthful
adjective

Old English hǣlth, health — adjectival suffix -ful. As a color modifier, healthful implies a clear-and-vital-and-wholesome quality where the hue carries the visual register of fresh-air-and-sunlight outdoor health-promoting environment. Sits at the crisp-and-wholesome end of the grid, parallel to salubrious and wholesome in usage.

Looped
modifier

Old French loupe, loop. As a color modifier, looped implies a hand-looped-and-curled quality, the visual register of hand-looped-knit-and-rope hand-looped-and-curled knit-and-rope-and-cord hand-looped-and-curled-loop-and-curl surfaces under hand-looped-and-curled knit-and-rope-and-cord working light. Sits at the modifier-and-texture end of the grid, parallel to coiled and twined 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.
