Wilhelm Kotarbinski keeps values measured and balanced, a hallmark of tonal restraint. Temperature is cool-dominant, with blue and green families claiming the largest areas. The absence of saturated colour is itself an expressive choice: this is a palette of restraint and atmosphere. The saturated accent, #6C3F2A, registers at 4.5% - sparse enough to feel like a deliberate surprise. The full value range is 68 units: broad enough to build convincing three-dimensional form. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively. Palette 5 sits within the larger chromatic argument that Wilhelm Kotarbinski's complete body of work advances.
