Mid-key values give Albert Dubois-Pillet its characteristic quietness - nothing blazes, nothing disappears. Blues and teal-greys govern the palette, lending it an aquatic or atmospheric quality. Chroma hovers near zero; colour declares itself through subtle shifts in hue rather than outright saturation. #5B3A3C functions as the palette's exclamation mark: highest chroma, lowest percentage (3.4%). 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. Palette 5 sits within the larger chromatic argument that Albert Dubois-Pillet's complete body of work advances.
