Alfred Sisley is strongly light-biased - shadow is suggested rather than declared. 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. The most saturated colour, #9F8C5F, is reserved to 5.3% of the surface, where it acts as a focal punctuation. The palette spans 52 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 9 of Alfred Sisley's sequence - a single chapter in a chromatic story told across many works.
