Ferdinand Hodler is high in key: pale, luminous, and filled with optical air. Warm and cool are kept in productive tension, creating the kind of chromatic harmony that sustains the eye. Every colour is desaturated; the palette proceeds through near-neutrals and gently-coloured greys. At 5.0%, #C4A566 carries the palette's sharpest chromatic charge: an accent that earns its place precisely because it is withheld. Spanning 43 units on the value axis, the palette achieves the balance between tonal flatness and fragmentation. Palette 4 sits within the larger chromatic argument that Ferdinand Hodler's complete body of work advances.
