Gustave Buchet sits in the centre of the value range, lending the palette a sense of even, sustained light. Gustave Buchet builds on cool foundations: the palette favours the blue-cyan-green arc. Chroma is held at a comfortable level - distinct colours, but no single hue is allowed to overwhelm. The highest-chroma note - #C2290F - appears at just 9.4%, deployed as a precision accent against the quieter ground. The value range spans 77 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. Palette 1 sits within the larger chromatic argument that Gustave Buchet's complete body of work advances.
