Cloaked Jambū

#400559
Notes

Cloaked Jambū (#400559) 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 (282°, 89%, 18%) places it in the highly saturated band at a dark lightness. Best used in small doses, like logos, CTAs, focus rings, or highlight text, where its saturation becomes a feature rather than noise. 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

Cloaked
adjective

Old French cloque, bell-cloak — past-participle of cloak. As a color modifier, cloaked implies a deep-fabric-shrouded quality where the hue is muffled by an enveloping textile-darkness. Sits at the deep-and-fabric end of the grid, parallel to mantled and hooded 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.

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.
