Wistful Jericho

#645773
Notes

Wistful Jericho (#645773) 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 (268°, 14%, 40%) places it in the muted 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

Wistful
adjective

Old English wishful, wishful. As a color modifier, wistful implies a hushed-and-melancholy-and-yearning quality where the hue carries the visual register of pre-modern Romantic-period nostalgic-and-yearning melancholic-mood color treatment. Sits at the hushed-and-melancholy end of the grid, parallel to nostalgic and plaintive in usage.

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.
