Genuine Dill Lagoon

#40b2e2
Notes

Genuine Dill Lagoon (#40B2E2) 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 (198°, 74%, 57%) 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 orange. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Genuine
adjective

Latin genuinus, natural, innate — used as a color modifier since the sixteenth century for hues that read as authentic rather than imitated. Genuine indigo, genuine ochre: moderate-to-high saturation combined with the optical impression of a hue from real pigment rather than synthetic dye. Sits at the crisp-bucket alongside true and honest.

Dill
modifier

Old English dile, aromatic-fern-leaf-herb. As a color modifier, dill implies a feathery-and-fresh-and-pickling quality, the visual register of Scandinavian-and-pickling-dill hand-feathery-and-fresh-and-pickling Scandinavian-and-pickling-dill-and-Polish-Eastern-European dill-and-feathery-and-fresh-and-pickling surfaces under Scandinavian-and-pickling-dill-and-Polish-Eastern-European Stockholm-and-Gdansk-and-Riga-pickling-jar Baltic-pickling-light. Sits at the modifier-and-flavor end of the grid, parallel to chive and anise 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.
