Darkness anchors Sebastiano del Piombo; light is rationed, creating dramatic contrast rather than open air. Heat pervades this palette; warm chromatic identities outweigh cool ones at almost every weight. All colours lean toward grey, building depth through value rather than colour punch. The dominant colour, #171318, takes 32.9% of the total area, establishing the overall mood before any other hue is introduced. #8C6540 functions as the palette's exclamation mark: highest chroma, lowest percentage (5.8%). At 66 units of value range, the palette has the tonal breadth to sustain complex spatial readings. This tonal restraint is characteristic of the Sebastiano del Piombo approach: colour serves light, not the reverse. In the context of Sebastiano del Piombo's full range of palettes, group 5 represents one movement in an ongoing chromatic dialogue.
