Darkness anchors Francesco Melzi; light is rationed, creating dramatic contrast rather than open air. Warm and cool are kept in productive tension, creating the kind of chromatic harmony that sustains the eye. Chroma hovers near zero; colour declares itself through subtle shifts in hue rather than outright saturation. Francesco Melzi gives 41.2% of the composition to a single #101011 - a decisive chromatic anchor. The highest-chroma note - #B1514C - appears at just 1.9%, deployed as a precision accent against the quieter ground. A value spread of 73 units gives the palette both depth and air - shadows are genuinely dark, lights genuinely light. The combination of low values, muted chroma, and compressed range is the signature of the Tonalist mode - painting as atmosphere. In the context of Francesco Melzi's full range of palettes, group 3 represents one movement in an ongoing chromatic dialogue.
