Grave Plum

#470b53
Notes

Grave Plum (#470B53) 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 (290°, 77%, 18%) places it in the highly saturated band at a dark lightness. Best used in small doses, like logos, CTAs, focus rings, or highlight text, where its saturation becomes a feature rather than noise. 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

Grave
adjective

Latin gravis, heavy — also the noun grave (burial pit). As a color modifier, grave implies a deep-and-formal seriousness where the hue carries weight beyond its lightness alone. Sits at the deep-and-solemn end of the grid, parallel to solemn and funereal in tone.

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.

Moderately saturated colors gain a small bump in P3 — the difference is usually visible side-by-side on wide-gamut hardware but won't change the character of the color.
