Charles Gleyre distributes its values across the middle register, creating harmony without high contrast. Heat pervades this palette; warm chromatic identities outweigh cool ones at almost every weight. Mid-saturation across the board: the palette has colour character without chromatic excess. The highest-chroma note - #EBAF8D - appears at just 6.6%, deployed as a precision accent against the quieter ground. The value range spans 61 units across the palette, providing the full gamut from deep shadow to near-white and ensuring clear tonal hierarchy. Palette 4 sits within the larger chromatic argument that Charles Gleyre's complete body of work advances.
