nude painting (nu) 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. #55392C functions as the palette's exclamation mark: highest chroma, lowest percentage (8.5%). The full value range is 55 units: broad enough to build convincing three-dimensional form.
