Stimulating Harīta

#40ad4f
Notes

Stimulating Harīta (#40AD4F) 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 (128°, 46%, 46%) 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

Stimulating
adjective

Latin stimulāns, spurring on — present-participle of stimulate, derived from stimulus (a goad). As a color modifier, stimulating implies a saturated-and-arousing-and-attentive quality where the hue increases visual-and-cognitive engagement. Sits at the bright-and-active end of the grid, parallel to invigorating and bracing in usage.

Harīta
noun

The Sanskrit word for yellow-green — used in classical Vedic texts for the green of Phyllanthus emblica (haritaki — Indian gooseberry) and the saffron-yellow-green of monsoon rice paddies. The color refers to a Vedic harīta description of new monsoon rice: a saturated, slightly yellow-green with the matte finish of fresh South Asian paddy.

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.
