The value structure of Jan de Bray is mid-key: quiet, controlled, and cohesive. Blues and teal-greys govern the palette, lending it an aquatic or atmospheric quality. All colours lean toward grey, building depth through value rather than colour punch. #2C2B26 claims 37.5% of the surface, functioning as the work's tonal foundation. The most saturated colour, #C79466, is reserved to 3.3% of the surface, where it acts as a focal punctuation. The full value range is 60 units: broad enough to build convincing three-dimensional form. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source. Jan de Bray's palette 1 carries its own internal logic while remaining in conversation with the artist's broader colour intelligence.
