Heavy Crocus

#5d0b56
Notes

Heavy Crocus (#5D0B56) 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 (305°, 79%, 20%) 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

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.

Crocus
noun

The genus Crocus — small autumn or spring corms that flower before their leaves emerge, push through snow in March, and include C. sativus, the source of saffron. The color refers to a fresh blue-violet spring crocus: a saturated, slightly violet-shifted deep blue with the satiny finish of a six-petaled cup catching morning light. Cooler than amethyst, warmer than iris, with the seasonal weight of a flower that arrives weeks before everything else.
