Paul Nash occupies the comfortable middle of the value scale, avoiding both extremes to hold the eye in a sustained middle grey. Temperature is cool-dominant, with blue and green families claiming the largest areas. Muted throughout, the palette achieves its effects through value and temperature rather than chromatic force. #131316 claims 25.3% of the surface, functioning as the work's tonal foundation. The highest-chroma note - #B13D3B - appears at just 0.7%, deployed as a precision accent against the quieter ground. The value range spans 62 units across the palette, providing the full gamut from deep shadow to near-white and ensuring clear tonal hierarchy. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. Paul Nash's palette 12 carries its own internal logic while remaining in conversation with the artist's broader colour intelligence.
