Buttoned Meek Lagoon

#2cb9da
Notes

Buttoned Meek Lagoon (#2CB9DA) 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 (191°, 70%, 51%) 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

Buttoned
adjective

Old French bouton, button — past-participle of button. As a color modifier, buttoned implies a clear-and-fastened-and-formal quality, the crisp color of Edwardian-period formal-attire fully-fastened-and-formally-dressed gentleman's-attire. Sits at the crisp-and-finished end of the grid, parallel to trim and pressed in usage.

Meek
modifier

Old Norse mjúkr, soft-and-gentle. As a color modifier, meek implies a hushed-and-self-effacing-and-quiet quality, the visual register of Beatitude-and-Quaker-meeting-meek hand-bowed-and-self-effacing-and-quiet Beatitude-and-Quaker-meeting-and-monastic-cloister meek-and-bowed-and-quieted surfaces under Beatitude-and-Quaker-meeting-and-monastic-cloister hush-and-bowed-vigil candle-lit-light. Sits at the modifier-and-mood end of the grid, parallel to coy and mute 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.
