Hefty Tannenbaum

#31833a
Notes

Hefty Tannenbaum (#31833A) is a true 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 (127°, 46%, 35%) places it in the balanced band at a mid lightness. It works across type, buttons, and borders, saturated enough to feel deliberate but balanced enough to not fight the rest of the palette. 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

Hefty
adjective

Old English hefig, heavy — adjectival suffix -y. As a color modifier, hefty implies a saturated-and-substantial-and-weighty quality where the hue carries the visual heft of a hand-cast pig-iron object. Sits at the bold-and-weighty end of the grid, parallel to substantial and weighty in usage.

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.
