Sebastiano del Piombo keeps values measured and balanced, a hallmark of tonal restraint. Blues and teal-greys govern the palette, lending it an aquatic or atmospheric quality. Saturation is deliberately withheld - the beauty here lies in the near-monochromatic gradations rather than colour difference. #B9A78E functions as the palette's exclamation mark: highest chroma, lowest percentage (10.2%). 60 units of value range underpin the palette's structural clarity: the eye always knows where light falls. 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 3 of Sebastiano del Piombo's sequence - a single chapter in a chromatic story told across many works.
