The value structure of William Henry Huddle 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. The highest-chroma note - #A66E4B - appears at just 5.2%, deployed as a precision accent against the quieter ground. Value range is moderate at 44 units - enough contrast for legibility, not so much as to fragment the tonal unity. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source. Palette 3 sits within the larger chromatic argument that William Henry Huddle's complete body of work advances.
