Alfred Sisley works in the upper reaches of the value scale, creating an atmosphere of brightness and expansiveness. Cool tones set the register here - the blues and greens easily outweigh any warm accents. Muted throughout, the palette achieves its effects through value and temperature rather than chromatic force. #B4B1A5 at 32.8% of the palette: an overwhelming presence that pulls all other colours into its gravitational field. At 3.9%, #C0AC6B carries the palette's sharpest chromatic charge: an accent that earns its place precisely because it is withheld. The full value range is 61 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. In the context of Alfred Sisley's full range of palettes, group 4 represents one movement in an ongoing chromatic dialogue.
