The value structure of Utagawa Toyokuni is mid-key: quiet, controlled, and cohesive. Utagawa Toyokuni tilts toward cool - blues and silver-greys carry the structural weight. Saturation is deliberately withheld - the beauty here lies in the near-monochromatic gradations rather than colour difference. #BAA885 functions as the palette's exclamation mark: highest chroma, lowest percentage (11.2%). The palette spans 49 value units: a measured range that delivers coherence over drama. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. Palette 4 sits within the larger chromatic argument that Utagawa Toyokuni's complete body of work advances.
