John Martin sits in the centre of the value range, lending the palette a sense of even, sustained light. Temperature is cool-dominant, with blue and green families claiming the largest areas. The absence of saturated colour is itself an expressive choice: this is a palette of restraint and atmosphere. #A29058 functions as the palette's exclamation mark: highest chroma, lowest percentage (3.5%). The value range spans 58 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. John Martin's palette 6 carries its own internal logic while remaining in conversation with the artist's broader colour intelligence.
