Tartarean Blueberry

#2b3c92
Notes

Tartarean Blueberry (#2B3C92) is a true blue 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 (230°, 54%, 37%) places it in the balanced band at a mid lightness. It works across type, buttons, and borders, saturated enough to feel deliberate but balanced enough to not fight the rest of the palette. For a confident two-color system, pair it with its complementary amber. 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.

Blueberry
noun

The genus Vaccinium — North American native berry shrubs cultivated since the early twentieth century. The fruit's deep blue-purple skin is colored by anthocyanin and the protective bloom of waxy yeast cells. The color refers to a fresh wild blueberry: a saturated, slightly cool deep blue-violet with the powdery finish of waxy fruit surface.
