Pietro Lorenzetti distributes its values across the middle register, creating harmony without high contrast. Cool tones set the register here - the blues and greens easily outweigh any warm accents. Chroma is kept low across all colours, producing the soft, enveloping quality that characterises tonal painting. #A0603C delivers the chromatic peak at only 5.0% - a small shot of colour with outsized visual impact. The value range spans 61 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. Palette 1 sits within the larger chromatic argument that Pietro Lorenzetti's complete body of work advances.
