Giovanni Battista Piazzetta is built on dark foundations, with values clustered toward shadow. Blues and teal-greys govern the palette, lending it an aquatic or atmospheric quality. Muted throughout, the palette achieves its effects through value and temperature rather than chromatic force. A single dominant - #303028 at 31.6% - sets the character of the whole composition. #6F4719 functions as the palette's exclamation mark: highest chroma, lowest percentage (2.5%). The value range spans 78 units across the palette, providing the full gamut from deep shadow to near-white and ensuring clear tonal hierarchy. The combination of low values, muted chroma, and compressed range is the signature of the Tonalist mode - painting as atmosphere. In the context of Giovanni Battista Piazzetta's full range of palettes, group 1 represents one movement in an ongoing chromatic dialogue.
