Edgar Degas occupies the comfortable middle of the value scale, avoiding both extremes to hold the eye in a sustained middle grey. Cool tones set the register here - the blues and greens easily outweigh any warm accents. Saturation is deliberately withheld - the beauty here lies in the near-monochromatic gradations rather than colour difference. #A47A57 functions as the palette's exclamation mark: highest chroma, lowest percentage (8.6%). From deepest dark to palest light, the palette traverses 65 units of the value scale - a span that creates natural depth. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. Palette 4 sits within the larger chromatic argument that Edgar Degas's complete body of work advances.
