Plain Hiddenite
Plain Hiddenite (#AEEBA8) is a soft green with a pastel character. It reads calm and airy, with enough chroma to feel intentional rather than washed out. Its HSL profile (115°, 63%, 79%) 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
Latin planus, flat, level — used as a color modifier since the medieval period for hues that read as undecorated and direct. Plain white, plain blue: moderate saturation, no shift, no surface effect. Sits in the crisp-bucket center, with the implication of restraint rather than absence.
The chromium-rich green variety of spodumene — discovered in 1879 in Hiddenite, North Carolina, where it was named for mineralogist William E. Hidden. The color refers to a faceted hiddenite: a saturated, slightly cool yellow-green with the gem's signature internal life. Cooler than tsavorite.
