James McNeill Whistler is strongly light-biased - shadow is suggested rather than declared. Temperature is cool-dominant, with blue and green families claiming the largest areas. Mid-saturation across the board: the palette has colour character without chromatic excess. #D2CA6C at 23.8% is both the most chromatic and one of the largest colours in the palette - chroma as mass rather than as highlight. At 69 units of value range, the palette has the tonal breadth to sustain complex spatial readings. 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 James McNeill Whistler's full range of palettes, group 8 represents one movement in an ongoing chromatic dialogue.
