Showy Hiddenite

#57bf5b
Notes

Showy Hiddenite (#57BF5B) 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 (122°, 45%, 55%) 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 violet. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Showy
adjective

Old English scēawian, to look at — adjectival suffix -y. As a color modifier, showy implies a saturated-and-attention-grabbing quality, the bright color of Las-Vegas-and-Broadway neon-and-marquee theatrical-display lighting. Sits at the bright-and-flamboyant end of the grid, parallel to flamboyant and splashy in usage.

Hiddenite
noun

The chromium-rich green variety of spodumene — discovered in 1879 in Hiddenite, North Carolina, where it was named for mineralogist William E. Hidden. The color refers to a faceted hiddenite: a saturated, slightly cool yellow-green with the gem's signature internal life. Cooler than tsavorite.

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.
