Ernst Stuckelberg occupies the comfortable middle of the value scale, avoiding both extremes to hold the eye in a sustained middle grey. Ernst Stuckelberg orchestrates warmth above all else - reds, ambers, and siennas take the lead. Every colour is desaturated; the palette proceeds through near-neutrals and gently-coloured greys. Ernst Stuckelberg gives 32.7% of the composition to a single #2A2724 - a decisive chromatic anchor. At 7.0%, #1C1108 carries the palette's sharpest chromatic charge: an accent that earns its place precisely because it is withheld. The full value range is 58 units: broad enough to build convincing three-dimensional form. Ernst Stuckelberg's palette 4 carries its own internal logic while remaining in conversation with the artist's broader colour intelligence.
