The value structure of Jean Baptiste Vanmour is mid-key: quiet, controlled, and cohesive. Warm and cool are kept in productive tension, creating the kind of chromatic harmony that sustains the eye. Chroma is kept low across all colours, producing the soft, enveloping quality that characterises tonal painting. Only 6.2% is devoted to #624020, yet that small allocation delivers the palette's entire chromatic tension. The full value range is 55 units: broad enough to build convincing three-dimensional form. Jean Baptiste Vanmour's palette 4 carries its own internal logic while remaining in conversation with the artist's broader colour intelligence.
