Fading Hardal

#636a52
Notes

Fading Hardal (#636A52) is a true lime 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 (78°, 13%, 37%) 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 indigo. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Fading
adjective

Old French fader, to fade — present-participle of fade. As a color modifier, fading implies a hushed-and-receding-and-thinning quality where the hue carries the visual register of sun-faded-and-light-bleached multi-month-or-decade gradual-fading color-amplitude. Sits at the hushed-and-fading end of the grid, parallel to waning and dimming in usage.

Hardal
noun

The Turkish word for mustard — used both for the condiment and the slightly muted gold-yellow of the hardal sauces of Anatolian kitchens. The color refers to a fresh-mixed hardal paste: a saturated, slightly muted gold-yellow with the dusty finish of mustard-seed powder. The Turkish cousin of mustard.
