Tartarean Jericho

#2a182e
Notes

Tartarean Jericho (#2A182E) is a deep violet 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 (289°, 31%, 14%) 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 green. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Tartarean
adjective

Greek Tartárean, of Tartarus — adjectival form of Tartarus, the deepest pit beneath Hades. As a color modifier, tartarean implies a literary-classical-deep-darkness quality, parallel to Stygian and Cimmerian in poetic register. Sits at the deepest end of the grid, with classical-literary connotations.

Jericho
noun

Ancient Levantine city (continuously occupied since 9000 BCE) — and a secondary Tyrian-purple production site supplying the inland Judean and Idumean courts. Jericho color refers to a Jericho-produced Tyrian-purple-dyed talith prayer shawl: a saturated, slightly cool deep violet with the matte finish of multi-bath Murex shellfish dye on Levantine wool. Slightly warmer than Tyre itself.
