Murky Petunia

#231138
Notes

Murky Petunia (#231138) is a deep indigo 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 (268°, 53%, 14%) places it in the balanced 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 lime. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Murky
adjective

From Old Norse myrkr, darkness — sharing root with mirkwood. Murky implies low value combined with reduced clarity — the deep brown-greens of pond water, the dim interior of a smoke-blackened bar. Sits at the deep-and-dirtied end of the grid, where the color is both dark and slightly clouded.

Petunia
noun

Petunia × atkinsiana, the modern garden hybrid bred from South American Petunia species in the nineteenth century — now the most-planted annual bedding flower in North America. The color refers to a deep purple petunia in summer container bloom: a saturated, slightly red-shifted deep purple with the satiny finish of trumpet-shaped flowers. Cooler than orchid, warmer than violet, with the bedding-plant weight of a genus bred for nearly endless color and continuous bloom.
