Stimulating Chrysoprase

#6ad181
Notes

Stimulating Chrysoprase (#6AD181) is a true green 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 (133°, 53%, 62%) 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

Stimulating
adjective

Latin stimulāns, spurring on — present-participle of stimulate, derived from stimulus (a goad). As a color modifier, stimulating implies a saturated-and-arousing-and-attentive quality where the hue increases visual-and-cognitive engagement. Sits at the bright-and-active end of the grid, parallel to invigorating and bracing in usage.

Chrysoprase
noun

An apple-green variety of chalcedony — colored by trace nickel, mined principally in Australia, Poland, and Madagascar. The color refers to a polished Australian chrysoprase: a saturated, slightly cool yellow-green-blue with the matte translucency of cryptocrystalline silica. Cooler than apple.
