Mary Cassatt is high in key: pale, luminous, and filled with optical air. Mary Cassatt balances warm and cool with remarkable evenness, giving the composition its characteristic vibrancy. Every colour is desaturated; the palette proceeds through near-neutrals and gently-coloured greys. The most saturated colour, #D9BBAE, is reserved to 14.7% of the surface, where it acts as a focal punctuation. A value spread of 69 units gives the palette both depth and air - shadows are genuinely dark, lights genuinely light. Palette 3 sits within the larger chromatic argument that Mary Cassatt's complete body of work advances.
