Lurid Bloodstone

#6da51b
Notes

Lurid Bloodstone (#6DA51B) 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 (84°, 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

Lurid
adjective

Latin lūridus, pale-yellow / sickly — sharing root with lūror (yellowish-pallor). As a color modifier, lurid implies a saturated-and-shocking-and-sickly-bright quality, the bright color of Penny-Dreadful-and-Pulp-Fiction sensational-cover-art bright-and-pulpy printing. Sits at the bright-and-shocking end of the grid, parallel to garish and gaudy in usage.

Bloodstone
noun

A dark green chalcedony with red iron-oxide flecks — used in classical antiquity for engraved seals and Christian-era ornament (the red flecks symbolizing Christ's blood). Also called heliotrope. The color refers to a polished bloodstone cabochon: a saturated, slightly muted dark yellow-green with the optical complexity of red-flecked chalcedony.
