Frantic Arugula

#66b346
Notes

Frantic Arugula (#66B346) 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 (102°, 44%, 49%) 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.

Arugula
noun

Eruca vesicaria, the Mediterranean mustard-family green — peppery and bitter, eaten as rocket in British English and rucola in Italian. Arugula color refers to fresh wild arugula leaves: a saturated, slightly muted deep yellow-green with the matte finish of small notched leaves.

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.
