The value structure of Oskar Kokoschka is mid-key: quiet, controlled, and cohesive. Blues and teal-greys govern the palette, lending it an aquatic or atmospheric quality. Muted throughout, the palette achieves its effects through value and temperature rather than chromatic force. The most saturated colour, #AB583C, is reserved to 6.0% of the surface, where it acts as a focal punctuation. At 65 units of value range, the palette has the tonal breadth to sustain complex spatial readings. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source. Oskar Kokoschka's palette 4 carries its own internal logic while remaining in conversation with the artist's broader colour intelligence.
