Antonietta Brandeis is high in key: pale, luminous, and filled with optical air. Cool tones set the register here - the blues and greens easily outweigh any warm accents. Chroma hovers near zero; colour declares itself through subtle shifts in hue rather than outright saturation. Only 7.1% is devoted to #965D36, yet that small allocation delivers the palette's entire chromatic tension. A value spread of 56 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. These proportions encode Antonietta Brandeis's instinctive sense of how much of each quality the eye can hold.
