Withering Tulip

#645565
Notes

Withering Tulip (#645565) 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 (296°, 9%, 36%) 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 green. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Withering
adjective

Old English wedrian, to expose to weather — present-participle of wither. As a color modifier, withering implies a hushed-and-drying-and-fading quality where the hue carries the visual register of Autumn-October-leaf-and-wildflower gradually-drying-and-fading color-amplitude. Sits at the hushed-and-fading end of the grid, parallel to wilted and fading in usage.

Tulip
noun

The genus Tulipa — Central Asian bulbs cultivated in Ottoman gardens, brought to Europe in the sixteenth century, and famously the subject of tulipomania in the 1630s Dutch Republic. The color refers to a deep purple Tulipa hybrid in spring bloom: a saturated, slightly red-shifted deep purple with the satiny finish of a six-petaled goblet. Cooler than orchid, warmer than indigo, with the cultivation history of a flower that briefly cost more than houses.
