Alfred Sisley is high in key: pale, luminous, and filled with optical air. Yellow, ochre, sienna: warm hues that Alfred Sisley deploys as the palette's primary energy. Chroma is kept low across all colours, producing the soft, enveloping quality that characterises tonal painting. Only 4.6% is devoted to #8F5E35, yet that small allocation delivers the palette's entire chromatic tension. A value spread of 56 units gives the palette both depth and air - shadows are genuinely dark, lights genuinely light. In the context of Alfred Sisley's full range of palettes, group 5 represents one movement in an ongoing chromatic dialogue.
