Cagnaccio di San Pietro distributes its values across the middle register, creating harmony without high contrast. Cool hues prevail: blues, greens, and greys anchor the palette's emotional temperature. A restrained, mid-chroma palette: every hue is present and legible, but nothing shouts. #9EAA8B at 34.6% of the palette: an overwhelming presence that pulls all other colours into its gravitational field. The saturated accent, #4B70AB, registers at 6.2% - sparse enough to feel like a deliberate surprise. The palette spans 40 value units: a measured range that delivers coherence over drama. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source. Cagnaccio di San Pietro's palette 4 carries its own internal logic while remaining in conversation with the artist's broader colour intelligence.
