Resilient Hyacinthine

#781768
Notes

Resilient Hyacinthine (#781768) is a deep magenta 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 (310°, 68%, 28%) 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

Resilient
adjective

Latin resiliēns, springing-back — present-participle of resilīre. As a color modifier, resilient implies a saturated-and-recovering-and-flexible quality where the hue maintains its strength under visual pressure. Sits at the bold-and-resilient end of the grid, parallel to tough and hardy in usage.

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.
