Giovanni Antonio Boltraffio distributes its values across the middle register, creating harmony without high contrast. Yellow, ochre, sienna: warm hues that Giovanni Antonio Boltraffio deploys as the palette's primary energy. Colours are neither washed out nor blazing; they occupy the productive middle ground of the chroma scale. The saturated accent, #C34530, registers at 4.0% - sparse enough to feel like a deliberate surprise. A value spread of 65 units gives the palette both depth and air - shadows are genuinely dark, lights genuinely light. The palette is recognisably Giovanni Antonio Boltraffio's own: particular in its temperature, chroma, and the economy of its brightest note.
