Dyed Erythrite
Dyed Erythrite (#51196F) 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 (279°, 63%, 27%) 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
Old English dēag, dye — past-participle of dye. As a color modifier, dyed implies a hue produced by deliberate textile-coloration in multi-bath fermentation-or-mordant-fixation processes, distinguished from natural-or-incidental color. Sits at the deep-and-pigmented end of the grid, parallel to stained and pigmented in usage.
Cobalt bloom, a hydrated cobalt arsenate mineral that forms as a secondary alteration product on cobalt-rich ores. The mineral is sometimes called cobalt arsenate hydrate. Erythrite color refers to a freshly fractured Schneeberg erythrite crystal cluster: a saturated, slightly cool deep violet with the matte finish of acicular hydrated cobalt-arsenate crystals. Named for the Greek erythros (red), though the mineral is purple-violet.
