Sure Tannenbaum

#315b26
Notes

Sure Tannenbaum (#315B26) 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 (108°, 41%, 25%) 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.

Tannenbaum
noun

The German word for fir tree — particularly the Abies and Picea trees decorated as Weihnachtsbaum in the German Christmas tradition. Tannenbaum color refers to fresh fir foliage in a Bavarian forest in December: a deep, slightly cool dark green with the resinous finish of conifer needles.
