Joseph Wright keeps values measured and balanced, a hallmark of tonal restraint. Joseph Wright builds on cool foundations: the palette favours the blue-cyan-green arc. Chroma is kept low across all colours, producing the soft, enveloping quality that characterises tonal painting. #DAD8CB at 28.3% of the palette: an overwhelming presence that pulls all other colours into its gravitational field. The highest-chroma note - #B38049 - appears at just 3.4%, deployed as a precision accent against the quieter ground. The value range spans 74 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. This is palette 4 of Joseph Wright's sequence - a single chapter in a chromatic story told across many works.
