Steeped Hyacinthine

#641783
Notes

Steeped Hyacinthine (#641783) is a deep violet 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 (283°, 70%, 30%) 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 green. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Steeped
adjective

Old English stēpan, to dip / soak — past-participle of steep. As a color modifier, steeped implies the deep-and-saturation-rich quality of dye-bath-saturated textile, where the hue has reached fiber-saturation. Sits at the deep-and-saturated end of the grid, parallel to infused and suffused.

Hyacinthine
noun

Purple dye of late-classical antiquity, mentioned in Pliny the Elder's Natural History (77 CE) as a substitute for the more expensive Tyrian purple, derived from a combination of woad and madder. Hyacinthine color refers to a hyacinthine-dyed Roman toga praetexta border: a saturated, slightly cool deep violet with the matte finish of multi-bath woad-and-madder overdye on woolen toga cloth. Slightly cooler than Tyrian.

Moderately saturated colors gain a small bump in P3 — the difference is usually visible side-by-side on wide-gamut hardware but won't change the character of the color.
