Manorial Blueberry

#373b92
Notes

Manorial Blueberry (#373B92) 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 (237°, 45%, 39%) 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

Manorial
adjective

Latin manōrium, dwelling — adjectival suffix -al, derived from manēre (to remain). As a color modifier, manorial implies a saturated-and-aristocratic-and-rural quality, the deep-rich color of pre-modern English manor-house livery-and-tapestry tradition. Sits at the bold-and-aristocratic end of the grid, parallel to lordly and patrician.

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.
