Sebastiano del Piombo occupies the comfortable middle of the value scale, avoiding both extremes to hold the eye in a sustained middle grey. Sebastiano del Piombo orchestrates warmth above all else - reds, ambers, and siennas take the lead. Saturation is deliberately withheld - the beauty here lies in the near-monochromatic gradations rather than colour difference. #221E1D at 27.5% of the palette: an overwhelming presence that pulls all other colours into its gravitational field. The highest-chroma note - #7D1A14 - appears at just 3.7%, deployed as a precision accent against the quieter ground. 55 units of value range underpin the palette's structural clarity: the eye always knows where light falls. The palette is recognisably Sebastiano del Piombo's own: particular in its temperature, chroma, and the economy of its brightest note.
