Rich Bishop

#9b36a9
Notes

Rich Bishop (#9B36A9) 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 (293°, 52%, 44%) 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

Rich
adjective

Old French riche, wealthy, abundant — applied to color since the medieval period for hues that read as plentiful in pigment. Rich red, rich brown: the implication is depth combined with saturation, a color that gives the eye more to absorb. Sits at the saturated mid-light corner of the engine's grid, slightly warmer than bold and deeper than vivid.

Bishop
noun

Greek epískopos via Latin episcopus, overseer — the ecclesiastical office whose Roman-Catholic and Anglican vesture includes a deep-violet cassock under white rochet and chimere. Bishop color refers to a contemporary Roman-Catholic episcopal cassock: a saturated, slightly cool deep violet with the matte finish of vat-dyed liturgical wool. Distinct from the deep-red cardinal cassock and the white papal cassock.
