Willem Koekkoek keeps values measured and balanced, a hallmark of tonal restraint. 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. At 7.0%, #956C40 carries the palette's sharpest chromatic charge: an accent that earns its place precisely because it is withheld. The full value range is 58 units: broad enough to build convincing three-dimensional form. In the context of Willem Koekkoek's full range of palettes, group 1 represents one movement in an ongoing chromatic dialogue.
