The value structure of Mary Cassatt is mid-key: quiet, controlled, and cohesive. Mary Cassatt orchestrates warmth above all else - reds, ambers, and siennas take the lead. The absence of saturated colour is itself an expressive choice: this is a palette of restraint and atmosphere. #2C2A2A claims 26.9% of the surface, functioning as the work's tonal foundation. The most saturated colour, #9E392C, is reserved to 5.2% of the surface, where it acts as a focal punctuation. The full value range is 64 units: broad enough to build convincing three-dimensional form. Palette 6 sits within the larger chromatic argument that Mary Cassatt's complete body of work advances.
