Charles M. Russell sits in the centre of the value range, lending the palette a sense of even, sustained light. 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. #9898C1 delivers the chromatic peak at only 2.7% - a small shot of colour with outsized visual impact. The value range spans 70 units across the palette, providing the full gamut from deep shadow to near-white and ensuring clear tonal hierarchy. Palette 13 sits within the larger chromatic argument that Charles M. Russell's complete body of work advances.
