Decisive Jericho

#ac45b1
Notes

Decisive Jericho (#AC45B1) is a true violet 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 (297°, 44%, 48%) 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 green. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Decisive
adjective

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.

Jericho
noun

Ancient Levantine city (continuously occupied since 9000 BCE) — and a secondary Tyrian-purple production site supplying the inland Judean and Idumean courts. Jericho color refers to a Jericho-produced Tyrian-purple-dyed talith prayer shawl: a saturated, slightly cool deep violet with the matte finish of multi-bath Murex shellfish dye on Levantine wool. Slightly warmer than Tyre itself.

This color is chromatic enough that authoring it as P3 native (instead of clamping to sRGB) gives a perceptibly more saturated render on wide-gamut displays — modern Macs, iPhones, iPads, and most recent OLED laptops.
