Masaccio keeps values measured and balanced, a hallmark of tonal restraint. Masaccio keeps warm and cool in parity, a balance that lends the work a perceptual shimmer. Chroma is held at a comfortable level - distinct colours, but no single hue is allowed to overwhelm. The highest-chroma note - #582E14 - appears at just 5.5%, deployed as a precision accent against the quieter ground. The palette spans 47 value units: a measured range that delivers coherence over drama. Together these qualities point to the open-air Impressionist method: recording light rather than local colour. Palette 3 sits within the larger chromatic argument that Masaccio's complete body of work advances.
