Mid-key values give Jan Cossiers its characteristic quietness - nothing blazes, nothing disappears. Temperature is cool-dominant, with blue and green families claiming the largest areas. Chroma is kept low across all colours, producing the soft, enveloping quality that characterises tonal painting. At 3.5%, #DAC9AB carries the palette's sharpest chromatic charge: an accent that earns its place precisely because it is withheld. At 62 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. This is palette 1 of Jan Cossiers's sequence - a single chapter in a chromatic story told across many works.
