Caffeinated Hauyne
Caffeinated Hauyne (#21C894) 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 (161°, 72%, 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 red. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
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.
A blue-to-green variety of the lazurite mineral group — used in classical Egyptian and Mesoamerican blue pigments and modern fine jewelry. The color refers to a polished hauyne specimen: a saturated, slightly cool deep blue-green with the matte finish of sodium-aluminum silicate.
