Wilhelm Kray sits in the centre of the value range, lending the palette a sense of even, sustained light. Wilhelm Kray builds on cool foundations: the palette favours the blue-cyan-green arc. Saturation is deliberately withheld - the beauty here lies in the near-monochromatic gradations rather than colour difference. The saturated accent, #926141, registers at 4.0% - sparse enough to feel like a deliberate surprise. At 63 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. In the context of Wilhelm Kray's full range of palettes, group 3 represents one movement in an ongoing chromatic dialogue.
