Charles M. Russell is strongly light-biased - shadow is suggested rather than declared. Temperature is cool-dominant, with blue and green families claiming the largest areas. Saturation is deliberately withheld - the beauty here lies in the near-monochromatic gradations rather than colour difference. The dominant colour, #E4D3AD, takes 33.4% of the total area, establishing the overall mood before any other hue is introduced. The most saturated colour, #95603E, is reserved to 1.9% of the surface, where it acts as a focal punctuation. At 66 units of value range, the palette has the tonal breadth to sustain complex spatial readings. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. Charles M. Russell's palette 6 carries its own internal logic while remaining in conversation with the artist's broader colour intelligence.
