Francis Danby 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. Chroma is kept low across all colours, producing the soft, enveloping quality that characterises tonal painting. Only 4.5% is devoted to #643A21, yet that small allocation delivers the palette's entire chromatic tension. The full value range is 63 units: broad enough to build convincing three-dimensional form. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source. The palette is a signature: Francis Danby's particular sense of value, warmth, and colour weight made legible.
