Calm Pflaume
Calm Pflaume (#8967A7) is a true indigo with a cool character. It leans cool, sitting on the blue, green, and violet side of the wheel. Quiet and dependable, a fit for product UI and data visualization. Its HSL profile (272°, 27%, 53%) 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
Latin calma, heat of the day — paradoxically drifted in Italian to mean stillness. Used as a color modifier since the seventeenth century for hues that read as untroubled. Calm blue, calm gray: moderate saturation combined with optical quiet. Sits at the crisp-bucket near quiet and steady.
German for plum (Prunus domestica) — particularly the deep-violet Hauszwetschge plum cultivar grown across southern Germany and Austria, the standard Pflaumenkuchen sheet-cake fruit. Pflaume color refers to a freshly picked Bavarian Hauszwetschge plum cross-section: a saturated, slightly cool deep violet with the matte finish of anthocyanin-rich plum skin and yellow-green flesh. Slightly warmer than French prune.
