The value structure of Expressionism is mid-key: quiet, controlled, and cohesive. The artist keeps warm and cool in parity, a balance that lends the work a perceptual shimmer. Saturation is deliberately withheld - the beauty here lies in the near-monochromatic gradations rather than colour difference. At 4.0%, #A66148 carries the palette's sharpest chromatic charge: an accent that earns its place precisely because it is withheld. Spanning 50 units on the value axis, the palette achieves the balance between tonal flatness and fragmentation.
