Mid-key values give Carolus-Duran its characteristic quietness - nothing blazes, nothing disappears. A distinctly cool atmosphere runs through this palette: sky, water, and mist given colour form. Chroma is kept low across all colours, producing the soft, enveloping quality that characterises tonal painting. Carolus-Duran gives 29.7% of the composition to a single #1A1922 - a decisive chromatic anchor. #E7D2C7 functions as the palette's exclamation mark: highest chroma, lowest percentage (2.7%). The value range spans 66 units across the palette, providing the full gamut from deep shadow to near-white and ensuring clear tonal hierarchy. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively. Palette 6 sits within the larger chromatic argument that Carolus-Duran's complete body of work advances.
