The value structure of Jules Breton is mid-key: quiet, controlled, and cohesive. Jules Breton tilts toward cool - blues and silver-greys carry the structural weight. Saturation is deliberately withheld - the beauty here lies in the near-monochromatic gradations rather than colour difference. #A9804B delivers the chromatic peak at only 3.7% - a small shot of colour with outsized visual impact. A value spread of 65 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. This is palette 3 of Jules Breton's sequence - a single chapter in a chromatic story told across many works.
