The value structure of Antoniazzo Romano is mid-key: quiet, controlled, and cohesive. Antoniazzo Romano builds on cool foundations: the palette favours the blue-cyan-green arc. Saturation is deliberately withheld - the beauty here lies in the near-monochromatic gradations rather than colour difference. Only 4.7% is devoted to #995444, yet that small allocation delivers the palette's entire chromatic tension. The value range spans 61 units across the palette, providing the full gamut from deep shadow to near-white and ensuring clear tonal hierarchy. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. Palette 3 sits within the larger chromatic argument that Antoniazzo Romano's complete body of work advances.
