Darkness anchors Joseph Wright; light is rationed, creating dramatic contrast rather than open air. Joseph Wright builds on cool foundations: the palette favours the blue-cyan-green arc. Chroma hovers near zero; colour declares itself through subtle shifts in hue rather than outright saturation. #0F120B claims 25.7% of the surface, functioning as the work's tonal foundation. At 2.0%, #B3631D carries the palette's sharpest chromatic charge: an accent that earns its place precisely because it is withheld. A value spread of 55 units gives the palette both depth and air - shadows are genuinely dark, lights genuinely light. This tonal restraint is characteristic of the Joseph Wright approach: colour serves light, not the reverse. This is palette 13 of Joseph Wright's sequence - a single chapter in a chromatic story told across many works.
