The value structure of Emile Renouf is mid-key: quiet, controlled, and cohesive. Temperature is cool-dominant, with blue and green families claiming the largest areas. Chroma is kept low across all colours, producing the soft, enveloping quality that characterises tonal painting. The saturated accent, #907A54, registers at 6.0% - sparse enough to feel like a deliberate surprise. At 51 units across the value scale, the palette keeps contrast readable without letting it dominate. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. This is palette 1 of Emile Renouf's sequence - a single chapter in a chromatic story told across many works.
