Piero della Francesca occupies the comfortable middle of the value scale, avoiding both extremes to hold the eye in a sustained middle grey. Temperature is cool-dominant, with blue and green families claiming the largest areas. Muted throughout, the palette achieves its effects through value and temperature rather than chromatic force. Only 2.9% is devoted to #AB5A3F, yet that small allocation delivers the palette's entire chromatic tension. The full value range is 59 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 Piero della Francesca's full range of palettes, group 2 represents one movement in an ongoing chromatic dialogue.
