The value structure of Henri-Francois Riesener is mid-key: quiet, controlled, and cohesive. Neither warm nor cool has the upper hand here; the equilibrium between the two generates the palette's visual energy. Saturation is deliberately withheld - the beauty here lies in the near-monochromatic gradations rather than colour difference. The highest-chroma note - #613811 - appears at just 7.8%, deployed as a precision accent against the quieter ground. At 62 units of value range, the palette has the tonal breadth to sustain complex spatial readings. In the context of Henri-Francois Riesener's full range of palettes, group 4 represents one movement in an ongoing chromatic dialogue.
