Paul Sandby is high in key: pale, luminous, and filled with optical air. Cool tones set the register here - the blues and greens easily outweigh any warm accents. Chroma hovers near zero; colour declares itself through subtle shifts in hue rather than outright saturation. The most saturated colour, #564C38, is reserved to 4.9% of the surface, where it acts as a focal punctuation. The value range spans 73 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. Paul Sandby's palette 3 carries its own internal logic while remaining in conversation with the artist's broader colour intelligence.
