Steeped Blueberry

#42358a
Notes

Steeped Blueberry (#42358A) 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 (249°, 45%, 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 yellow. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Steeped
adjective

Old English stēpan, to dip / soak — past-participle of steep. As a color modifier, steeped implies the deep-and-saturation-rich quality of dye-bath-saturated textile, where the hue has reached fiber-saturation. Sits at the deep-and-saturated end of the grid, parallel to infused and suffused.

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.
