The high-key values of William Williams give it an effulgent, almost bleached quality. A distinctly cool atmosphere runs through this palette: sky, water, and mist given colour form. Chroma is kept low across all colours, producing the soft, enveloping quality that characterises tonal painting. #CFC1A4 at 48.4% of the palette: an overwhelming presence that pulls all other colours into its gravitational field. At 5.2%, #9F8042 carries the palette's sharpest chromatic charge: an accent that earns its place precisely because it is withheld. The palette spans 51 value units: a measured range that delivers coherence over drama. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively. This is palette 3 of William Williams's sequence - a single chapter in a chromatic story told across many works.
