Incandescent Chrysoprase

#40e7b3
Notes

Incandescent Chrysoprase (#40E7B3) 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°, 78%, 58%) 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 red. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Incandescent
adjective

Latin incandēscēns, growing-hot — present-participle of incandēscere, sharing root with candere (to shine). As a color modifier, incandescent implies a saturated-and-glowing-hot quality, the bright color of tungsten-filament-glow incandescent-lamp light. Sits at the bright-and-warm end of the grid, parallel to glowing and blazing 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.
