Values in Alfred Sisley rest in the mid-range - neither dramatically lit nor steeped in shadow. Alfred Sisley builds on cool foundations: the palette favours the blue-cyan-green arc. Chroma is kept low across all colours, producing the soft, enveloping quality that characterises tonal painting. #634D34 functions as the palette's exclamation mark: highest chroma, lowest percentage (10.6%). From deepest dark to palest light, the palette traverses 64 units of the value scale - a span that creates natural depth. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively. This is palette 15 of Alfred Sisley's sequence - a single chapter in a chromatic story told across many works.
