Charles M. Russell occupies the comfortable middle of the value scale, avoiding both extremes to hold the eye in a sustained middle grey. Heat pervades this palette; warm chromatic identities outweigh cool ones at almost every weight. The absence of saturated colour is itself an expressive choice: this is a palette of restraint and atmosphere. The saturated accent, #E8E0DB, registers at 4.1% - sparse enough to feel like a deliberate surprise. The full value range is 65 units: broad enough to build convincing three-dimensional form. Palette 15 sits within the larger chromatic argument that Charles M. Russell's complete body of work advances.
