Looming Blueberry

#383c8b
Notes

Looming Blueberry (#383C8B) 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°, 43%, 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

Looming
adjective

Middle English lomen, to appear vaguely — present-participle of loom. As a color modifier, looming implies a deep-and-vague-and-imposing quality, the dark cool-gray of fog-veiled-and-distant cliff-or-mountain-mass against the sky. Sits at the deep-and-imposing end of the grid, parallel to imposing and towering.

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.
