Tartarean Pflaume

#571c78
Notes

Tartarean Pflaume (#571C78) is a deep indigo 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 (278°, 62%, 29%) 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 lime. 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.

Pflaume
noun

German for plum (Prunus domestica) — particularly the deep-violet Hauszwetschge plum cultivar grown across southern Germany and Austria, the standard Pflaumenkuchen sheet-cake fruit. Pflaume color refers to a freshly picked Bavarian Hauszwetschge plum cross-section: a saturated, slightly cool deep violet with the matte finish of anthocyanin-rich plum skin and yellow-green flesh. Slightly warmer than French prune.
