Stained Colchicum

#513763
Notes

Stained Colchicum (#513763) is a deep indigo with an earthy character. It leans grounded and natural, the kind of color that plays well with wood, clay, linen, and warm neutrals. Its HSL profile (275°, 29%, 30%) places it in the muted 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

Stained
adjective

Old French desteindre, to discolor — past-participle of stain. As a color modifier, stained implies a deep-pigment-and-permanent quality where the hue has bonded with the substrate fiber. Sits at the deep-and-pigmented end of the grid, parallel to dyed and suffused 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.
