Piero della Francesca sits in the centre of the value range, lending the palette a sense of even, sustained light. Cool hues prevail: blues, greens, and greys anchor the palette's emotional temperature. Chroma is kept low across all colours, producing the soft, enveloping quality that characterises tonal painting. #D6C397 functions as the palette's exclamation mark: highest chroma, lowest percentage (8.4%). The value range of 51 units sits in the comfortable middle: enough depth, enough light, neither extreme. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. Piero della Francesca's palette 6 carries its own internal logic while remaining in conversation with the artist's broader colour intelligence.
