Giotto keeps values measured and balanced, a hallmark of tonal restraint. Cool tones set the register here - the blues and greens easily outweigh any warm accents. Saturation is deliberately withheld - the beauty here lies in the near-monochromatic gradations rather than colour difference. #384655 at 4.5% is both the most chromatic and one of the largest colours in the palette - chroma as mass rather than as highlight. 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 11 of Giotto's sequence - a single chapter in a chromatic story told across many works.
