The value structure of Marie Bashkirtseff is mid-key: quiet, controlled, and cohesive. Cool hues prevail: blues, greens, and greys anchor the palette's emotional temperature. Saturation is deliberately withheld - the beauty here lies in the near-monochromatic gradations rather than colour difference. #2C2E14 at 25.2% of the palette: an overwhelming presence that pulls all other colours into its gravitational field. The highest-chroma note - #B9AA70 - appears at just 10.4%, deployed as a precision accent against the quieter ground. At 57 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. Palette 4 sits within the larger chromatic argument that Marie Bashkirtseff's complete body of work advances.
