Carlo Carra is strongly light-biased - shadow is suggested rather than declared. A distinctly cool atmosphere runs through this palette: sky, water, and mist given colour form. The absence of saturated colour is itself an expressive choice: this is a palette of restraint and atmosphere. At 7.3%, #C3B573 carries the palette's sharpest chromatic charge: an accent that earns its place precisely because it is withheld. A value spread of 65 units gives the palette both depth and air - shadows are genuinely dark, lights genuinely light. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. Palette 4 sits within the larger chromatic argument that Carlo Carra's complete body of work advances.
