Values in Eugene Boudin rest in the mid-range - neither dramatically lit nor steeped in shadow. Eugene Boudin builds on cool foundations: the palette favours the blue-cyan-green arc. Saturation is deliberately withheld - the beauty here lies in the near-monochromatic gradations rather than colour difference. The highest-chroma note - #3A2C19 - appears at just 8.0%, deployed as a precision accent against the quieter ground. A value spread of 58 units gives the palette both depth and air - shadows are genuinely dark, lights genuinely light. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source. Eugene Boudin's palette 18 carries its own internal logic while remaining in conversation with the artist's broader colour intelligence.
