Jean-Leon Gerome occupies the comfortable middle of the value scale, avoiding both extremes to hold the eye in a sustained middle grey. Temperature is cool-dominant, with blue and green families claiming the largest areas. Chroma hovers near zero; colour declares itself through subtle shifts in hue rather than outright saturation. The highest-chroma note - #9B4A23 - appears at just 1.7%, deployed as a precision accent against the quieter ground. At 65 units of value range, the palette has the tonal breadth to sustain complex spatial readings. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source. Palette 13 sits within the larger chromatic argument that Jean-Leon Gerome's complete body of work advances.
