Frenetic Skiff Chartreuse

#a9e98f
Notes

Frenetic Skiff Chartreuse (#A9E98F) is a soft green with a cool character. It leans cool, sitting on the blue, green, and violet side of the wheel. Quiet and dependable, a fit for product UI and data visualization. Its HSL profile (103°, 67%, 74%) places it in the balanced band at a light lightness. It works as a background wash, large-area fill, or soft illustration tone. Add a darker ink of the same hue when you need type over it. 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

Frenetic
adjective

Greek phrenitikós, frenzied — adjectival suffix -ic, derived from phrēn (mind). As a color modifier, frenetic implies a saturated-and-frenzied-and-active quality, the bright color of Hyper-Color-and-Memphis-Group 1980s-design saturated-and-active visual-rhythm. Sits at the bright-and-active end of the grid, parallel to frantic and manic in usage.

Skiff
modifier

Italian schifo, small-boat. As a color modifier, skiff implies a small-flat-bottomed-rowing-boat quality, the visual register of Cornish-and-Mediterranean-skiff hand-built small-flat-bottomed-rowing-and-sailing skiff-and-dinghy-and-rowboat maritime-architecture surfaces under Cornish-and-Mediterranean small-skiff-and-dinghy harbor-and-fishing light. Sits at the modifier-and-nautical end of the grid, parallel to sloop and hull in usage.

Chartreuse
noun

The yellow-green French liqueur made by Carthusian monks at the Grande Chartreuse monastery since 1737, from a recipe of 130 herbs known to only two living monks at any time. The color is the base spirit chartreuse jaune in a glass: a saturated, slightly green yellow that's brighter than lemon and warmer than lime. The liqueur gave the color its name, not the other way around.
