Low-key values are the structural spine of Johann Zoffany, giving it gravity and atmosphere. Johann Zoffany orchestrates warmth above all else - reds, ambers, and siennas take the lead. Colours are neither washed out nor blazing; they occupy the productive middle ground of the chroma scale. 25.2% of the palette belongs to #190C04, a concentration that makes it the unmistakable visual centre. The most saturated colour, #322607, is reserved to 8.9% of the surface, where it acts as a focal punctuation. A value spread of 58 units gives the palette both depth and air - shadows are genuinely dark, lights genuinely light. Johann Zoffany follows the old-master formula: deep values, warm underlighting, and chroma held in reserve for the focal point. Palette 4 sits within the larger chromatic argument that Johann Zoffany's complete body of work advances.
