Strobing Chrysocolla

#19b663
Notes

Strobing Chrysocolla (#19B663) 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°, 76%, 41%) 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

Strobing
adjective

Greek stróbos, whirling — present-participle of strobe. As a color modifier, strobing implies a saturated-and-pulse-flashing quality, the bright color of concert-strobe-light and photographic-strobe high-frequency-pulse light emission. Sits at the bright-and-flashing end of the grid, parallel to flashing and pulsating in usage.

Chrysocolla
noun

A copper-aluminum hydrous silicate — saturated blue-green, mined principally in copper-mineral deposits of Arizona, Israel, and the Democratic Republic of the Congo. The color refers to a polished chrysocolla cabochon: a saturated, slightly cool deep blue-green with the matte finish of secondary copper mineral. Cooler than malachite.

Moderately saturated colors gain a small bump in P3 — the difference is usually visible side-by-side on wide-gamut hardware but won't change the character of the color.
