Caffeinated Spearmint

#28c481
Notes

Caffeinated Spearmint (#28C481) is a true teal with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (154°, 66%, 46%) 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

Caffeinated
adjective

Modern French caféine — past-participle of caffeinate. As a color modifier, caffeinated implies a saturated-and-jumpy-and-active quality, the bright color of Red-Bull-and-Monster energy-drink-can label-design saturated-and-energizing palette. Sits at the bright-and-active end of the grid, parallel to jazzed and wired in usage.

Spearmint
noun

Mentha spicata, the mild green mint of Mediterranean kitchens — the lamb-sauce mint of British cooking, the mojito mint of Cuba, the karkadeh tea garnish of Egypt. The color refers to fresh spearmint leaves: a saturated, slightly cool green with the matte finish of trichome-rich foliage. Brighter than peppermint, lighter than basil, with the lighter aromatic profile of carvone instead of menthol.
