Sure Redwood

#25542a
Notes

Sure Redwood (#25542A) 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 (126°, 39%, 24%) 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 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.

Redwood
noun

Sequoia sempervirens, the coast redwood — the tallest tree species on Earth, native to the coastal fog belt of northern California. Redwood color refers to mature redwood needle foliage: a saturated, slightly cool deep green with the matte finish of fog-adapted needle foliage. Cooler than sequoia.
