The palette of Léon Bazile Perrault sits in the lower register of the value scale - dense, contained, and weighted. 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. 37.6% of the palette belongs to #12161C, a concentration that makes it the unmistakable visual centre. The most saturated colour, #9D8466, is reserved to 2.1% of the surface, where it acts as a focal punctuation. The value range spans 70 units across the palette, providing the full gamut from deep shadow to near-white and ensuring clear tonal hierarchy. Together these qualities place Léon Bazile Perrault firmly in the tonal tradition - concerned with mood and atmosphere rather than chromatic display. In the context of Léon Bazile Perrault's full range of palettes, group 6 represents one movement in an ongoing chromatic dialogue.
