Frantic Smaragdite

#33ac38
Notes

Frantic Smaragdite (#33AC38) is a true green with an earthy character. It leans grounded and natural, the kind of color that plays well with wood, clay, linen, and warm neutrals. Its HSL profile (122°, 54%, 44%) 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

Frantic
adjective

Greek phrenitikós, frenzied — adjectival suffix, sharing root with phrenitis (delirium). As a color modifier, frantic implies a saturated-and-rushed-and-overactive quality, the bright color of Memphis-Group 1980s-design over-the-top saturated visual-rhythm. Sits at the bright-and-active end of the grid, parallel to frenetic and manic in usage.

Smaragdite
noun

An emerald-green variety of amphibole — closely related to actinolite, found in metamorphic rocks of the Italian Alps. The color refers to a polished Italian smaragdite: a saturated, slightly muted deep green with the slight fibrous texture of amphibole crystallography.
