Mid-key values give Pietro Perugino its characteristic quietness - nothing blazes, nothing disappears. Yellow, ochre, sienna: warm hues that Pietro Perugino deploys as the palette's primary energy. Saturation is deliberately withheld - the beauty here lies in the near-monochromatic gradations rather than colour difference. The highest-chroma note - #9C794F - appears at just 6.1%, deployed as a precision accent against the quieter ground. From deepest dark to palest light, the palette traverses 61 units of the value scale - a span that creates natural depth. The palette is a signature: Pietro Perugino's particular sense of value, warmth, and colour weight made legible.
