Values in John Singleton Copley rest in the mid-range - neither dramatically lit nor steeped in shadow. A distinctly cool atmosphere runs through this palette: sky, water, and mist given colour form. Chroma hovers near zero; colour declares itself through subtle shifts in hue rather than outright saturation. Only 1.8% is devoted to #BA7546, yet that small allocation delivers the palette's entire chromatic tension. The full value range is 71 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. In the context of John Singleton Copley's full range of palettes, group 2 represents one movement in an ongoing chromatic dialogue.
