The value structure of Arthur Dove 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 saturated accent, #BEAD5A, registers at 2.0% - sparse enough to feel like a deliberate surprise. The full value range is 70 units: broad enough to build convincing three-dimensional form. Palette 4 sits within the larger chromatic argument that Arthur Dove's complete body of work advances.
