Buttoned Bow Mint

#37a781
Notes

Buttoned Bow Mint (#37A781) is a true teal with an earthy character. It leans grounded and natural, the kind of color that plays well with wood, clay, linen, and warm neutrals. Its HSL profile (160°, 50%, 44%) 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.

Bow
modifier

Old Norse bógr, bow / shoulder. As a color modifier, bow implies a ship's-front-prow quality, the visual register of Royal-Navy-and-merchant-marine-bow hand-built ship's-front-prow-and-figurehead bow-and-cutwater maritime-architecture surfaces under ship's-front-bow-and-prow maritime-headway light. Sits at the modifier-and-nautical end of the grid, parallel to prow and hull in usage.

Mint
noun

The genus Mentha — peppermint, spearmint, apple mint, water mint — the cooling herb whose menthol gives it that quality at the molecular level. The color refers to fresh peppermint leaves before drying: a clean, slightly cool green with the matte finish of trichome-rich leaf surface. Lighter than basil, cooler than parsley, with the mojito-and-Pimm's association of a herb tied to summer drinks across two continents.
