Mid-key values give Eugène Grasset its characteristic quietness - nothing blazes, nothing disappears. Blues and teal-greys govern the palette, lending it an aquatic or atmospheric quality. The absence of saturated colour is itself an expressive choice: this is a palette of restraint and atmosphere. The most saturated colour, #674443, is reserved to 6.4% of the surface, where it acts as a focal punctuation. At 65 units of value range, the palette has the tonal breadth to sustain complex spatial readings. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source. Palette 6 sits within the larger chromatic argument that Eugène Grasset's complete body of work advances.
