The value structure of Sassoferrato is mid-key: quiet, controlled, and cohesive. Heat pervades this palette; warm chromatic identities outweigh cool ones at almost every weight. The absence of saturated colour is itself an expressive choice: this is a palette of restraint and atmosphere. #223953 functions as the palette's exclamation mark: highest chroma, lowest percentage (4.7%). The value range spans 60 units across the palette, providing the full gamut from deep shadow to near-white and ensuring clear tonal hierarchy. Palette 5 sits within the larger chromatic argument that Sassoferrato's complete body of work advances.
