Mary Cassatt keeps values measured and balanced, a hallmark of tonal restraint. Temperature reads distinctly warm: the reds and earth tones from Mary Cassatt carry the compositional weight. The absence of saturated colour is itself an expressive choice: this is a palette of restraint and atmosphere. #191213 at 30.2% of the palette: an overwhelming presence that pulls all other colours into its gravitational field. #853F23 functions as the palette's exclamation mark: highest chroma, lowest percentage (6.6%). A value spread of 59 units gives the palette both depth and air - shadows are genuinely dark, lights genuinely light. Palette 18 sits within the larger chromatic argument that Mary Cassatt's complete body of work advances.
