Rudolf Koller sits in the centre of the value range, lending the palette a sense of even, sustained light. Rudolf Koller tilts toward cool - blues and silver-greys carry the structural weight. Chroma hovers near zero; colour declares itself through subtle shifts in hue rather than outright saturation. The saturated accent, #DDD6BE, registers at 9.1% - sparse enough to feel like a deliberate surprise. At 57 units of value range, the palette has the tonal breadth to sustain complex spatial readings. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. Rudolf Koller's palette 2 carries its own internal logic while remaining in conversation with the artist's broader colour intelligence.
