The value structure of John Duncan Fergusson is mid-key: quiet, controlled, and cohesive. A distinctly cool atmosphere runs through this palette: sky, water, and mist given colour form. Chroma is kept low across all colours, producing the soft, enveloping quality that characterises tonal painting. At 28.3%, #27242D functions less as a colour accent and more as a complete atmospheric environment. #B9AA2F delivers the chromatic peak at only 4.2% - a small shot of colour with outsized visual impact. The value range spans 65 units across the palette, providing the full gamut from deep shadow to near-white and ensuring clear tonal hierarchy. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source. Palette 1 sits within the larger chromatic argument that John Duncan Fergusson's complete body of work advances.
