Withering Twilight
Withering Twilight (#686F83) 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 (224°, 11%, 46%) 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 amber. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
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.
The transitional sky color in the half-hour after sunset — when direct sunlight has gone but the upper atmosphere still scatters reds, oranges, and finally deep blues. The color refers to the western sky at nautical twilight on a clear evening: a deep, slightly violet-shifted dark blue with the optical depth of a sky still receiving scattered light from below the horizon. Deeper than dawn, warmer than midnight.

Accessibility
How this color appears to viewers with the four major color-vision-deficiency types. Computed via the Machado (2009) physiologically-based model. If a tile matches the original, the color reads the same to that viewer.
The color used as foreground text against pure white and pure black, with the contrast ratio and WCAG 2.1 grade. Aim for AA (4.5:1) for body text and AA Large (3:1) for 18 pt+ headlines; AAA (7:1) is the gold standard for long-form reading surfaces.
Wide gamut
The CSS Color 4 wide-gamut form of this color. Both swatches render the same color on every display — the P3 form only diverges from sRGB when a designer pushes channels outside sRGB's reach.
This color sits well within the sRGB cube. P3 and sRGB share the gray axis and most desaturated tones, so a P3 display renders this identically to an sRGB display.
