Obsidian Laurel

#1b521f
Notes

Obsidian Laurel (#1B521F) 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 (124°, 50%, 21%) 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

Obsidian
noun

Volcanic glass — molten rhyolite cooled too quickly to crystallize. Mined since the Stone Age for blade-edges (sharper than surgical steel) and ground into mirrors by the Aztec priesthood for divination. The color refers to a polished obsidian flake from Mount Hekla or Glass Buttes, Oregon: a deep, slightly blue-shifted black with the high-gloss conchoidal fracture of natural glass. Cooler than onyx, glossier than coal.

Laurel
noun

Laurus nobilis, the bay laurel of the Mediterranean — sacred to Apollo and the source of the wreaths that crowned poets, generals, and Olympic victors. The color refers to mature laurel leaves: a deep, glossy green with the high shine of waxy cuticle and the slight blue-shift of dense chlorophyll. Darker than spinach, cooler than holly, with the classical weight of a tree that names poet laureate.

Moderately saturated colors gain a small bump in P3 — the difference is usually visible side-by-side on wide-gamut hardware but won't change the character of the color.
