Values in Post-Impressionism tilt decisively toward white, giving the palette its luminous character. The palette tilts toward cool - blues and silver-greys carry the structural weight. Saturation is measured and controlled, giving the palette presence without visual aggression. The most saturated colour, #9F7643, is reserved to 11.1% of the surface, where it acts as a focal punctuation. Spanning 51 units on the value axis, the palette achieves the balance between tonal flatness and fragmentation. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source.
