Auguste Herbin occupies the comfortable middle of the value scale, avoiding both extremes to hold the eye in a sustained middle grey. Auguste Herbin tilts toward cool - blues and silver-greys carry the structural weight. Chroma is kept low across all colours, producing the soft, enveloping quality that characterises tonal painting. #5B2C28 functions as the palette's exclamation mark: highest chroma, lowest percentage (7.5%). The full value range is 66 units: broad enough to build convincing three-dimensional form. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. Auguste Herbin's palette 6 carries its own internal logic while remaining in conversation with the artist's broader colour intelligence.
