Spartan Bittersweet

#892b14
Notes

Spartan Bittersweet (#892B14) is a deep red 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 (12°, 75%, 31%) 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 cyan. 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.

Bittersweet
noun

Celastrus scandens, the North American climbing vine whose autumn fruits split to reveal orange-red arils against yellow capsules. The color refers to ripe bittersweet berries in October: a saturated, slightly red orange with the matte finish of fall berry skin. Warmer than rust, drier than tangerine.
