Antique Groen

#45583e
Notes

Antique Groen (#45583E) is a deep 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 (104°, 17%, 29%) places it in the muted band at a dark lightness. It works well as a headline, icon, or deep background in an otherwise light layout, pairing cleanly with cream, bone, and warm neutrals. 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

Antique
adjective

Latin antiquus, ancient — used as a color modifier since the seventeenth century for hues that read as if from a previous era. Antique brass, antique rose: moderate-to-low saturation combined with the optical impression of historical patina. Sits at the hushed-bucket alongside aged and heritage.

Groen
noun

The Dutch word for green — used for the Hollands Groen of Delft Blue's complementary glaze and the green polders of Dutch reclaimed-land farmland. The color refers to a Delft-pottery green underglaze: a saturated, slightly cool green with the matte finish of fired tin-glaze. The Dutch cousin of green.
