Abundant Erythrite

#7b3188
Notes

Abundant Erythrite (#7B3188) is a true violet 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 (291°, 47%, 36%) places it in the balanced band at a mid lightness. It works across type, buttons, and borders, saturated enough to feel deliberate but balanced enough to not fight the rest of the palette. 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

Abundant
adjective

Latin abundāre, to overflow — present-participle of abound. As a color modifier, abundant implies a saturated-and-plentiful quality where the hue carries surplus visual richness beyond minimum requirement. Sits at the bold-and-saturated end of the grid, parallel to plentiful and bountiful.

Erythrite
noun

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.
