Pierre-Narcisse Guerin occupies the comfortable middle of the value scale, avoiding both extremes to hold the eye in a sustained middle grey. Temperature is cool-dominant, with blue and green families claiming the largest areas. All colours lean toward grey, building depth through value rather than colour punch. The highest-chroma note - #D4BE7A - appears at just 6.0%, deployed as a precision accent against the quieter ground. A value spread of 66 units gives the palette both depth and air - shadows are genuinely dark, lights genuinely light. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. Palette 6 sits within the larger chromatic argument that Pierre-Narcisse Guerin's complete body of work advances.
