Xu Beihong is high in key: pale, luminous, and filled with optical air. The dominant temperature is warm, with earth tones and fire-hues setting the emotional key. Chroma hovers near zero; colour declares itself through subtle shifts in hue rather than outright saturation. #D5B793 functions as the palette's exclamation mark: highest chroma, lowest percentage (5.3%). The value range spans 73 units across the palette, providing the full gamut from deep shadow to near-white and ensuring clear tonal hierarchy. Palette 1 sits within the larger chromatic argument that Xu Beihong's complete body of work advances.
