The high-key values of Lucien Pissarro give it an effulgent, almost bleached quality. Cool tones set the register here - the blues and greens easily outweigh any warm accents. Chroma hovers near zero; colour declares itself through subtle shifts in hue rather than outright saturation. At 7.4%, #ABA183 carries the palette's sharpest chromatic charge: an accent that earns its place precisely because it is withheld. Spanning 46 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. Palette 4 sits within the larger chromatic argument that Lucien Pissarro's complete body of work advances.
