Plainspoken Chartreuse

#c4ed9f
Notes

Plainspoken Chartreuse (#C4ED9F) is a soft lime with a pastel character. It reads calm and airy, with enough chroma to feel intentional rather than washed out. Its HSL profile (92°, 68%, 78%) 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 indigo. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Plainspoken
adjective

English compound plain + spoken — past-participle of speak. As a color modifier, plainspoken implies a clear-and-direct-and-straightforward quality where the hue carries the visual register of unembellished-honest declaration. Sits at the crisp-and-honest end of the grid, parallel to candid and direct 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.
