Burnt Blueberry

#3b378c
Notes

Burnt Blueberry (#3B378C) 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 (243°, 44%, 38%) 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 yellow. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Burnt
adjective

The past participle of burn used as a color modifier — most familiar in burnt sienna and burnt umber, the pigments produced by firing raw earth pigments to deepen and warm them. Implies a color that has been reduced and concentrated by heat, with the slight red-orange shift that high-temperature oxidation introduces. Sits in the dark-and-warm corner of the engine's grid.

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.
