Hyper Variscite

#63a91b
Notes

Hyper Variscite (#63A91B) is a true lime with a jewel character. It carries the deep, saturated richness of a gemstone. Authoritative and slightly formal, it works well for type and heavy UI elements. Its HSL profile (90°, 72%, 38%) 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 indigo. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Hyper
adjective

Greek hyper, over / beyond — sharing root with Latin super. As a color modifier, hyper implies a saturated-and-over-the-top-active quality where the hue exceeds normal visual amplitude with maximum-stimulation register. Sits at the bright-and-over-active end of the grid, parallel to manic and frenetic in usage.

Variscite
noun

A hydrated aluminum phosphate mineral — yellow-green to blue-green in color, mined principally in Utah and Australia. Often confused with low-grade turquoise. The color refers to a polished variscite cabochon: a soft, slightly muted yellow-green with the matte finish of opaque mineral. Cooler than prehnite.
