Buttoned Via Mint

#66cd97
Notes

Buttoned Via Mint (#66CD97) is a true teal with a cool character. It leans cool, sitting on the blue, green, and violet side of the wheel. Quiet and dependable, a fit for product UI and data visualization. Its HSL profile (149°, 51%, 60%) 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 magenta. 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.

Via
modifier

Latin via, road-or-way. As a color modifier, via implies a Latin-road-and-Roman-Via-Appia quality, the visual register of Roman-Via-Appia-and-Via-Aemilia hand-Latin-road-and-Roman-Via-Appia Roman-Via-Appia-and-Via-Aemilia-and-Via-Egnatia via-and-Latin-road surfaces under Roman-Via-Appia-and-Via-Aemilia-and-Via-Egnatia Republican-Rome-and-imperial-road-network basalt-paved-Roman-road-light. Sits at the modifier-and-Latin end of the grid, parallel to arbor and domus 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.
