Tenebrous Berry

#313951
Notes

Tenebrous Berry (#313951) is a deep 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 (225°, 25%, 25%) places it in the muted band at a dark lightness. It works well as a headline, icon, or deep background in an otherwise light layout, pairing cleanly with cream, bone, and warm neutrals. 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

Tenebrous
adjective

Latin tenebrōsus, full of darkness — derived from tenebrae (the deepening shadows of evening prayer service). As a color modifier, tenebrous implies a literary-poetic register for deep-shadowed darkness, where the hue is overwhelmed by ambient gloom. Sits at the deep-and-cool end of the grid, near Stygian but with painterly-baroque connotations.

Berry
noun

A general-purpose color name for the deep blue-purple of Vaccinium blueberries, Sambucus elderberries, and the Aronia black-chokeberries that mark hedgerows in autumn. The color refers to a ripe wild blueberry's bloom-coated skin: a deep, slightly violet-shifted blue with the powdery finish of waxy fruit. Cooler than wine, warmer than indigo, with the foraged-fruit specificity of a word that covers half-a-dozen species.
