The value structure of Charles M. Russell is mid-key: quiet, controlled, and cohesive. Heat pervades this palette; warm chromatic identities outweigh cool ones at almost every weight. Chroma is kept low across all colours, producing the soft, enveloping quality that characterises tonal painting. The saturated accent, #CAA992, registers at 8.1% - sparse enough to feel like a deliberate surprise. The full value range is 72 units: broad enough to build convincing three-dimensional form. Charles M. Russell's palette 12 carries its own internal logic while remaining in conversation with the artist's broader colour intelligence.
