The value structure of Pinturicchio is mid-key: quiet, controlled, and cohesive. Pinturicchio builds on cool foundations: the palette favours the blue-cyan-green arc. Saturation is deliberately withheld - the beauty here lies in the near-monochromatic gradations rather than colour difference. The most saturated colour, #A58553, is reserved to 10.5% of the surface, where it acts as a focal punctuation. From deepest dark to palest light, the palette traverses 57 units of the value scale - a span that creates natural depth. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source. This is palette 1 of Pinturicchio's sequence - a single chapter in a chromatic story told across many works.
