The value structure of Sanyu is mid-key: quiet, controlled, and cohesive. Heat pervades this palette; warm chromatic identities outweigh cool ones at almost every weight. Chroma hovers near zero; colour declares itself through subtle shifts in hue rather than outright saturation. #68302C claims 25.8% of the surface, functioning as the work's tonal foundation. #C9BF9C functions as the palette's exclamation mark: highest chroma, lowest percentage (12.5%). 48 units of value spread create a palette that is varied but unified - contrast in the service of harmony. This is palette 7 of Sanyu's sequence - a single chapter in a chromatic story told across many works.
