Values in Jean-Leon Gerome rest in the mid-range - neither dramatically lit nor steeped in shadow. Jean-Leon Gerome keeps warm and cool in parity, a balance that lends the work a perceptual shimmer. Mid-range chroma keeps the palette grounded - colourful but not strident. #558AA9 at 30.6% of the palette: an overwhelming presence that pulls all other colours into its gravitational field. The highest-chroma note - #BE7340 - appears at just 5.4%, deployed as a precision accent against the quieter ground. A value spread of 66 units gives the palette both depth and air - shadows are genuinely dark, lights genuinely light. The combination of mid-to-high key, balanced temperature, and elevated chroma is characteristic of Impressionist observation: light broken into its component hues. Palette 9 sits within the larger chromatic argument that Jean-Leon Gerome's complete body of work advances.
