Mid-key values give Alfred Sisley its characteristic quietness - nothing blazes, nothing disappears. Blues and teal-greys govern the palette, lending it an aquatic or atmospheric quality. Every colour is desaturated; the palette proceeds through near-neutrals and gently-coloured greys. The most saturated colour, #AC9766, is reserved to 3.1% of the surface, where it acts as a focal punctuation. The value range spans 60 units across the palette, providing the full gamut from deep shadow to near-white and ensuring clear tonal hierarchy. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively. In the context of Alfred Sisley's full range of palettes, group 17 represents one movement in an ongoing chromatic dialogue.
