The value structure of Giulio Romano is mid-key: quiet, controlled, and cohesive. Blues and teal-greys govern the palette, lending it an aquatic or atmospheric quality. Chroma is kept low across all colours, producing the soft, enveloping quality that characterises tonal painting. #4A3422 delivers the chromatic peak at only 9.2% - a small shot of colour with outsized visual impact. The value range spans 62 units across the palette, providing the full gamut from deep shadow to near-white and ensuring clear tonal hierarchy. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively. In the context of Giulio Romano's full range of palettes, group 5 represents one movement in an ongoing chromatic dialogue.
