Hollowed Plum

#620668
Notes

Hollowed Plum (#620668) 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 (296°, 89%, 22%) 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

Hollowed
adjective

Old English holh, hollow — past-participle of hollow. As a color modifier, hollowed implies the deep-and-cavernous-and-architectural quality of carved-out-cave-and-tunnel interior, particularly the Cappadocian and Lalibela hand-carved rock-cut churches and underground cities. Sits at the deep-and-architectural end of the grid, parallel to cavernous with hand-carved register.

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.
