Easy Honed Lagoon

#3dc0d9
Notes

Easy Honed Lagoon (#3DC0D9) 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°, 67%, 55%) 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

Easy
adjective

Old French aisié, comfortable, at rest — used as a color modifier since the eighteenth century for hues that read as visually undemanding. Easy beige, easy gray: moderate saturation combined with optical restfulness. Sits at the crisp-bucket center alongside calm and settled.

Honed
modifier

Old English hǣnan, to-sharpen. As a color modifier, honed implies a sharp-edged-and-polished quality, the visual register of Sheffield-and-Solingen-honed-blade hand-honed-and-sharpened-and-polished steel-and-iron-and-bronze Sheffield-and-Solingen-honed-blade surfaces under Sheffield-and-Solingen hand-honed-and-sharpened-blade workshop-light. Sits at the modifier-and-texture end of the grid, parallel to buffed and gloss 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.
