Pompeo Batoni distributes its values across the middle register, creating harmony without high contrast. Heat pervades this palette; warm chromatic identities outweigh cool ones at almost every weight. The absence of saturated colour is itself an expressive choice: this is a palette of restraint and atmosphere. #3A271D claims 31.6% of the surface, functioning as the work's tonal foundation. The highest-chroma note - #E7DFBF - appears at just 2.5%, deployed as a precision accent against the quieter ground. 66 units of value range underpin the palette's structural clarity: the eye always knows where light falls. This is palette 4 of Pompeo Batoni's sequence - a single chapter in a chromatic story told across many works.
