Brunel Neuville distributes its values across the middle register, creating harmony without high contrast. Heat pervades this palette; warm chromatic identities outweigh cool ones at almost every weight. Chroma is kept low across all colours, producing the soft, enveloping quality that characterises tonal painting. The most saturated colour, #6B2A1F, is reserved to 4.2% of the surface, where it acts as a focal punctuation. The palette spans 45 value units: a measured range that delivers coherence over drama. In the context of Brunel Neuville's full range of palettes, group 4 represents one movement in an ongoing chromatic dialogue.
