Spartan Pine

#3f941b
Notes

Spartan Pine (#3F941B) is a deep green with a jewel character. It carries the deep, saturated richness of a gemstone. Authoritative and slightly formal, it works well for type and heavy UI elements. Its HSL profile (102°, 69%, 34%) 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

Spartan
adjective

Greek Spartiátēs, of Sparta — adjectival suffix referring to the Lacedaemonian warrior city. As a color modifier, spartan implies a saturated-and-disciplined-and-formal quality, the deep-rich color of Spartan-hoplite military-class crimson-and-bronze armor-and-cloak. Sits at the bold-and-formal end of the grid, parallel to austere and stern in tone.

Pine
noun

The genus Pinus, conifers spread across nearly every continent — white, ponderosa, Scots, sugar — distinguished from spruce by needle clusters bound at the base. The color refers to mature pine needles in late summer: a saturated, slightly muted green with the resinous warmth of pine oil. Deeper than spruce, warmer than fir, with the unmistakable association of a forest where the ground is bare but the canopy never empties.
