Pietro Perugino keeps values measured and balanced, a hallmark of tonal restraint. Pietro Perugino tilts toward cool - blues and silver-greys carry the structural weight. Chroma is kept low across all colours, producing the soft, enveloping quality that characterises tonal painting. #AC603A functions as the palette's exclamation mark: highest chroma, lowest percentage (4.0%). The full value range is 58 units: broad enough to build convincing three-dimensional form. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively. In the context of Pietro Perugino's full range of palettes, group 5 represents one movement in an ongoing chromatic dialogue.
