Mid-key values give Frans Hals its characteristic quietness - nothing blazes, nothing disappears. Temperature reads distinctly warm: the reds and earth tones from Frans Hals carry the compositional weight. Chroma is kept low across all colours, producing the soft, enveloping quality that characterises tonal painting. #1A1715 at 30.5% of the palette: an overwhelming presence that pulls all other colours into its gravitational field. At 2.1%, #A17152 carries the palette's sharpest chromatic charge: an accent that earns its place precisely because it is withheld. At 71 units of value range, the palette has the tonal breadth to sustain complex spatial readings. This is palette 4 of Frans Hals's sequence - a single chapter in a chromatic story told across many works.
