The high-key values of Joseph Wright give it an effulgent, almost bleached quality. Joseph Wright tilts toward cool - blues and silver-greys carry the structural weight. Chroma is moderate: colours carry enough saturation to be read as colour, but the palette stops well short of garish intensity. At 7.0%, #6F4F2D carries the palette's sharpest chromatic charge: an accent that earns its place precisely because it is withheld. The full value range is 58 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 Joseph Wright's full range of palettes, group 1 represents one movement in an ongoing chromatic dialogue.
