Mid-key values give Xu Beihong 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. #583A25 functions as the palette's exclamation mark: highest chroma, lowest percentage (8.6%). 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. Xu Beihong's palette 6 carries its own internal logic while remaining in conversation with the artist's broader colour intelligence.
