Sure Normandy

#375b32
Notes

Sure Normandy (#375B32) 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 (113°, 29%, 28%) 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

Sure
adjective

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.

Normandy
noun

The French northwestern region — and the saturated green of Pays d'Auge apple-orchard country and the rolling green hills of the bocage Normand. Normandy refers to a Norman countryside in late spring: a saturated, slightly cool deep yellow-green with the matte finish of well-watered dairy pasture.
