Rugged Jambū

#7b1473
Notes

Rugged Jambū (#7B1473) 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 (305°, 72%, 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

Rugged

Sits at the bold-and-weathered end of the grid, parallel to tough and sinewy in usage.

Jambū
noun

Sanskrit जम्बू, the rose-apple (Syzygium jambos) — the eponymous fruit of Jambūdvīpa, the Continent of the Jambu Tree in Hindu and Buddhist cosmology, and a stock floral motif in Sanskrit poetry. Jambū color refers to a freshly cut Syzygium jambos drupe: a saturated, slightly cool deep violet with the matte finish of anthocyanin-rich fruit-flesh on the cut surface.
