The value structure of Antoine-Francois Callet 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. Muted throughout, the palette achieves its effects through value and temperature rather than chromatic force. #483A1D functions as the palette's exclamation mark: highest chroma, lowest percentage (9.8%). A value spread of 76 units gives the palette both depth and air - shadows are genuinely dark, lights genuinely light. Palette 4 sits within the larger chromatic argument that Antoine-Francois Callet's complete body of work advances.
