Henri Martin distributes its values across the middle register, creating harmony without high contrast. A distinctly cool atmosphere runs through this palette: sky, water, and mist given colour form. Saturation is deliberately withheld - the beauty here lies in the near-monochromatic gradations rather than colour difference. #97533B functions as the palette's exclamation mark: highest chroma, lowest percentage (4.2%). At 43 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. Henri Martin's palette 6 carries its own internal logic while remaining in conversation with the artist's broader colour intelligence.
