Heavy Plum

#301151
Notes

Heavy Plum (#301151) is a deep indigo 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 (269°, 65%, 19%) 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

Heavy
adjective

Old English hefig, weighty — cognate with heave. Used as a color modifier since at least the seventeenth century to indicate weight in saturation as much as value: heavy with pigment, heavy-bodied. In the engine's adjective grid, heavy sits alongside deep and plush in the dark-and-saturated quadrant. Closer to a fabric description than a pure value word.

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.
