Values in Gustave Loiseau rest in the mid-range - neither dramatically lit nor steeped in shadow. Blues and teal-greys govern the palette, lending it an aquatic or atmospheric quality. Saturation is deliberately withheld - the beauty here lies in the near-monochromatic gradations rather than colour difference. 25.1% of the palette belongs to #A0A998, a concentration that makes it the unmistakable visual centre. Only 6.8% is devoted to #C6C0A3, yet that small allocation delivers the palette's entire chromatic tension. Value range is moderate at 43 units - enough contrast for legibility, not so much as to fragment the tonal unity. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source. Gustave Loiseau's palette 12 carries its own internal logic while remaining in conversation with the artist's broader colour intelligence.
