The value structure of Mainie Jellette is mid-key: quiet, controlled, and cohesive. Mainie Jellette orchestrates warmth above all else - reds, ambers, and siennas take the lead. Chroma is kept low across all colours, producing the soft, enveloping quality that characterises tonal painting. The saturated accent, #7A574D, registers at 11.2% - sparse enough to feel like a deliberate surprise. Value range is moderate at 50 units - enough contrast for legibility, not so much as to fragment the tonal unity. In the context of Mainie Jellette's full range of palettes, group 3 represents one movement in an ongoing chromatic dialogue.
