Withering Skullcap

#556e85
Notes

Withering Skullcap (#556E85) is a true azure 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 (209°, 22%, 43%) 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 orange. 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.

Skullcap
noun

The genus Scutellariaskullcap, mint-family perennials whose helmet-shaped blue flowers and herbal medicinal properties have been used in Chinese, North American, and European traditional medicine. The color refers to a fresh S. baicalensis bloom: a saturated, slightly cool deep blue-violet with the matte finish of bilateral bracted flower.
