Antoine Chintreuil is high in key: pale, luminous, and filled with optical air. Cool tones set the register here - the blues and greens easily outweigh any warm accents. Chroma hovers near zero; colour declares itself through subtle shifts in hue rather than outright saturation. The highest-chroma note - #968847 - appears at just 4.3%, deployed as a precision accent against the quieter ground. At 47 units across the value scale, the palette keeps contrast readable without letting it dominate. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. Antoine Chintreuil's palette 1 carries its own internal logic while remaining in conversation with the artist's broader colour intelligence.
