The value structure of Thomas Cole 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. At 3.7%, #5B3226 carries the palette's sharpest chromatic charge: an accent that earns its place precisely because it is withheld. The full value range is 75 units: broad enough to build convincing three-dimensional form. In the context of Thomas Cole's full range of palettes, group 10 represents one movement in an ongoing chromatic dialogue.
