Nicolas Poussin sits in the centre of the value range, lending the palette a sense of even, sustained light. Nicolas Poussin tilts toward cool - blues and silver-greys carry the structural weight. All colours lean toward grey, building depth through value rather than colour punch. The most saturated colour, #9C7C4E, is reserved to 6.2% of the surface, where it acts as a focal punctuation. Spanning 53 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. This is palette 12 of Nicolas Poussin's sequence - a single chapter in a chromatic story told across many works.
