Grounded Plum

#791b7b
Notes

Grounded Plum (#791B7B) is a deep violet with a jewel character. It carries the deep, saturated richness of a gemstone. Authoritative and slightly formal, it works well for type and heavy UI elements. Its HSL profile (299°, 64%, 29%) 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 green. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Grounded
adjective

Old English grund, bottom / foundation — past-participle of ground. As a color modifier, grounded implies a saturated-and-foundational quality where the hue anchors the surrounding palette through its weighty presence. Sits at the bold-and-balanced end of the grid, parallel to centered and anchored.

Plum
noun

Prunus domestica, the European plum cultivated since at least the time of Greek and Roman orchards. The color refers to the skin of a ripe Damson or Methley plum at peak ripeness: a deep, slightly red-shifted purple-blue with the slight bloom of waxy fruit surface. Cooler than mulberry, warmer than indigo, with the orchard weight of a fruit whose skin and flesh are different colors — and the skin is the namesake.
