The value structure of Jean-Adrien Guignet is mid-key: quiet, controlled, and cohesive. Jean-Adrien Guignet tilts toward cool - blues and silver-greys carry the structural weight. All colours lean toward grey, building depth through value rather than colour punch. #A08A3D functions as the palette's exclamation mark: highest chroma, lowest percentage (7.5%). The value range spans 56 units across the palette, providing the full gamut from deep shadow to near-white and ensuring clear tonal hierarchy. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source. Jean-Adrien Guignet's palette 1 carries its own internal logic while remaining in conversation with the artist's broader colour intelligence.
