Decisive Jambū
Decisive Jambū (#633A98) is a true indigo 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 (266°, 45%, 41%) 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 lime. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
From the Latin decidere, to cut off — used as a modifier for colors that read as firm and final. Decisive black, decisive red: the implication is that the color has settled on its position and won't drift. Sits in the bold-bucket corner alongside resolute, with a slightly sharper edge.
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.

Accessibility
How this color appears to viewers with the four major color-vision-deficiency types. Computed via the Machado (2009) physiologically-based model. If a tile matches the original, the color reads the same to that viewer.
The color used as foreground text against pure white and pure black, with the contrast ratio and WCAG 2.1 grade. Aim for AA (4.5:1) for body text and AA Large (3:1) for 18 pt+ headlines; AAA (7:1) is the gold standard for long-form reading surfaces.
Wide gamut
The CSS Color 4 wide-gamut form of this color. Both swatches render the same color on every display — the P3 form only diverges from sRGB when a designer pushes channels outside sRGB's reach.
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.
