Alfred Sisley distributes its values across the middle register, creating harmony without high contrast. Alfred Sisley tilts toward cool - blues and silver-greys carry the structural weight. Every colour is desaturated; the palette proceeds through near-neutrals and gently-coloured greys. At 7.5%, #4B3E31 carries the palette's sharpest chromatic charge: an accent that earns its place precisely because it is withheld. 56 units of value range underpin the palette's structural clarity: the eye always knows where light falls. 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 18 of Alfred Sisley's sequence - a single chapter in a chromatic story told across many works.
