The value structure of Wilhelm Kotarbinski is mid-key: quiet, controlled, and cohesive. Yellow, ochre, sienna: warm hues that Wilhelm Kotarbinski deploys as the palette's primary energy. Every colour is desaturated; the palette proceeds through near-neutrals and gently-coloured greys. The saturated accent, #E0D0BC, registers at 8.3% - sparse enough to feel like a deliberate surprise. A value spread of 61 units gives the palette both depth and air - shadows are genuinely dark, lights genuinely light. This is palette 9 of Wilhelm Kotarbinski's sequence - a single chapter in a chromatic story told across many works.
