Restful Aubergine

#665a78
Notes

Restful Aubergine (#665A78) 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 (264°, 14%, 41%) 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

Restful
adjective

An adjectival form of rest — used as a color modifier since the seventeenth century for hues that read as visually relaxing. Restful green, restful blue: low-to-moderate saturation combined with optical calmness. Sits at the hushed-bucket alongside quiet and gentle.

Aubergine
noun

The French and British name for the eggplant — borrowed from the Catalan albergínia and ultimately from the Sanskrit vātiṅgaṇa. Aubergine as a color name carries with it the slightly more aristocratic register of the European-language version of the word. The color refers to the same fruit as eggplant but shifted slightly redder in popular usage: a saturated, slightly red-shifted very deep purple with the polished finish of waxy fruit. Cooler than wine, warmer than indigo.
