Soaked Colchicum

#581f7d
Notes

Soaked Colchicum (#581F7D) 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 (276°, 60%, 31%) 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

Soaked
adjective

Old English sūcian, to suck up liquid — past-participle of soak. As a color modifier, soaked implies a deep-saturation quality where the hue has reached fiber-saturation in dyed textile. Sits at the deep-and-saturated end of the grid, parallel to drenched and steeped in usage.

Colchicum
noun

Autumn crocus (Colchicum autumnale) — a Colchicaceae bulb native to Colchis (modern Georgia) whose deep-violet six-tepalled corolla emerges leafless in late autumn, named for the home of Medea. Colchicum color refers to a fully opened Colchicum autumnale corolla on a Cotswold meadow: a saturated, slightly cool deep violet with the velvet finish of fresh six-tepalled chalice-corolla. The plant is the source of colchicine, used to treat gout.
