Wilhelm Leibl is low-key throughout, a quality associated with Nocturnal Bister - deep shadows dominate the composition. The dominant temperature is warm, with earth tones and fire-hues setting the emotional key. All colours lean toward grey, building depth through value rather than colour punch. Wilhelm Leibl gives 31.8% of the composition to a single #1D1314 - a decisive chromatic anchor. At 3.1%, #D99566 carries the palette's sharpest chromatic charge: an accent that earns its place precisely because it is withheld. The value range spans 67 units across the palette, providing the full gamut from deep shadow to near-white and ensuring clear tonal hierarchy. Together these qualities place Wilhelm Leibl firmly in the tonal tradition - concerned with mood and atmosphere rather than chromatic display. This is palette 6 of Wilhelm Leibl's sequence - a single chapter in a chromatic story told across many works.
