Tucked Tufted Lagoon

#3db5d6
Notes

Tucked Tufted Lagoon (#3DB5D6) 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 (193°, 65%, 54%) 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

Tucked
adjective

Old English tūcian, to torment / pull — past-participle of tuck. As a color modifier, tucked implies a clear-and-fitted-and-arranged quality where the hue carries the visual register of carefully-tucked-and-neatly-fitted shirt-into-trouser dress-attire. Sits at the crisp-and-finished end of the grid, parallel to trim and pressed in usage.

Tufted
modifier

Old French touffe, tuft. As a color modifier, tufted implies a hand-tufted-and-puffed quality, the visual register of Edwardian-and-Belle-Époque-tufted-upholstery hand-tufted-and-puffed-and-upholstered velvet-and-silk-and-leather tufted-and-puffed-upholstery surfaces under Edwardian-and-Belle-Époque hand-tufted-upholstery-and-cushion light. Sits at the modifier-and-texture end of the grid, parallel to fluff and flock 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.
