Mid-key values give Andrea Pisano its characteristic quietness - nothing blazes, nothing disappears. Yellow, ochre, sienna: warm hues that Andrea Pisano deploys as the palette's primary energy. Muted throughout, the palette achieves its effects through value and temperature rather than chromatic force. Only 8.8% is devoted to #574132, yet that small allocation delivers the palette's entire chromatic tension. A value spread of 71 units gives the palette both depth and air - shadows are genuinely dark, lights genuinely light. These proportions encode Andrea Pisano's instinctive sense of how much of each quality the eye can hold.
