Pompeo Batoni occupies the comfortable middle of the value scale, avoiding both extremes to hold the eye in a sustained middle grey. Yellow, ochre, sienna: warm hues that Pompeo Batoni deploys as the palette's primary energy. Saturation is deliberately withheld - the beauty here lies in the near-monochromatic gradations rather than colour difference. #633621 delivers the chromatic peak at only 11.9% - a small shot of colour with outsized visual impact. From deepest dark to palest light, the palette traverses 73 units of the value scale - a span that creates natural depth. This is palette 5 of Pompeo Batoni's sequence - a single chapter in a chromatic story told across many works.
