Authoritative Nepal

#669d25
Notes

Authoritative Nepal (#669D25) 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 (88°, 62%, 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

Authoritative
adjective

Latin auctōritāt-, authority — adjectival suffix -ive. As a color modifier, authoritative implies a saturated-and-formal-imperative quality where the hue carries decisional weight and institutional credibility. Sits at the bold-and-authoritative end of the grid, parallel to commanding and magisterial in usage.

Nepal
noun

The Himalayan kingdom — and the terraced green of Nepalese rice and millet farms climbing the Annapurna foothills. Nepal color refers to a Pokhara terraced farm in monsoon season: a saturated, slightly yellow yellow-green with the matte finish of mid-altitude paddy.
