Caffeinated Artemisia

#15b760
Notes

Caffeinated Artemisia (#15B760) 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 (148°, 79%, 40%) places it in the highly saturated band at a mid lightness. Best used in small doses, like logos, CTAs, focus rings, or highlight text, where its saturation becomes a feature rather than noise. 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.

Artemisia
noun

The genus Artemisia — sage-and-wormwood-and-mugwort relatives whose silver-green leaves define Mediterranean dry-garden landscaping. The color refers to a fresh Artemisia ludoviciana cultivated in a Provençal garden: a soft, slightly cool gray-green with the matte velvet finish of pubescent silver leaf.
