Eugene Boudin is high-key - luminous, open, and weighted toward light. 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. At 5.6%, #483B2C carries the palette's sharpest chromatic charge: an accent that earns its place precisely because it is withheld. A value spread of 64 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 4 carries its own internal logic while remaining in conversation with the artist's broader colour intelligence.
