Sure Verdant
Sure Verdant (#19723D) is a deep green 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 (144°, 64%, 27%) places it in the balanced 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 magenta. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
Old French seur, certain — used as a color modifier since the medieval period for hues that read as confident and stable. Sure red, sure blue: moderate saturation combined with optical commitment. Sits at the crisp-bucket center alongside steady and true.
From the Latin viridis, green, through the French verdoyant. Verdant describes lushness — the saturated chlorophyll greenness of a thoroughly watered landscape after rain. The color refers to that idealized peak-summer green: a saturated, slightly cool green with the optical density of fully irrigated foliage. Deeper than meadow, cooler than basil, with the literary weight of a word that almost always appears in pastoral or paradisiacal contexts.
