The value structure of Marmaduke Cradock 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. Only 14.0% is devoted to #483825, yet that small allocation delivers the palette's entire chromatic tension. Value range is moderate at 49 units - enough contrast for legibility, not so much as to fragment the tonal unity. Palette 4 sits within the larger chromatic argument that Marmaduke Cradock's complete body of work advances.
