Substantial Jericho
Substantial Jericho (#722B91) 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 (282°, 54%, 37%) 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
Latin substantia, substance — adjectival suffix -al, derived from sub-stāre (to stand under). As a color modifier, substantial implies a saturated-and-weighty-and-material quality where the hue carries visual mass and presence. Sits at the bold-and-weighty end of the grid, parallel to weighty and hefty in usage.
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.
