Giovanni Segantini is high in key: pale, luminous, and filled with optical air. A distinctly cool atmosphere runs through this palette: sky, water, and mist given colour form. All colours lean toward grey, building depth through value rather than colour punch. Giovanni Segantini gives 33.8% of the composition to a single #E1EBE6 - a decisive chromatic anchor. At 5.6%, #E1D6C6 carries the palette's sharpest chromatic charge: an accent that earns its place precisely because it is withheld. The value range spans 64 units across the palette, providing the full gamut from deep shadow to near-white and ensuring clear tonal hierarchy. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. Palette 4 sits within the larger chromatic argument that Giovanni Segantini's complete body of work advances.
