The value structure of Henri Martin is mid-key: quiet, controlled, and cohesive. Temperature is cool-dominant, with blue and green families claiming the largest areas. Mid-saturation across the board: the palette has colour character without chromatic excess. The most saturated colour, #D3C18D, is reserved to 7.3% of the surface, where it acts as a focal punctuation. The palette spans 45 value units: a measured range that delivers coherence over drama. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively. Palette 4 sits within the larger chromatic argument that Henri Martin's complete body of work advances.
