Mid-key values give Wilhelm Kotarbinski its characteristic quietness - nothing blazes, nothing disappears. Yellow, ochre, sienna: warm hues that Wilhelm Kotarbinski deploys as the palette's primary energy. Saturation is deliberately withheld - the beauty here lies in the near-monochromatic gradations rather than colour difference. The highest-chroma note - #735345 - appears at just 10.3%, deployed as a precision accent against the quieter ground. The value range spans 66 units across the palette, providing the full gamut from deep shadow to near-white and ensuring clear tonal hierarchy. This is palette 4 of Wilhelm Kotarbinski's sequence - a single chapter in a chromatic story told across many works.
