Mid-key values give Giovanni Lanfranco its characteristic quietness - nothing blazes, nothing disappears. Cool tones set the register here - the blues and greens easily outweigh any warm accents. Muted throughout, the palette achieves its effects through value and temperature rather than chromatic force. #684D1F is not a small accent - at 5.0% it qualifies as a major presence and gives the palette its chromatic identity. The full value range is 68 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. The palette is recognisably Giovanni Lanfranco's own: particular in its temperature, chroma, and the economy of its brightest note.
