John Closterman distributes its values across the middle register, creating harmony without high contrast. The palette achieves thermal balance - reds and blues, ochres and greens, each holding the other in check. Chroma is kept low across all colours, producing the soft, enveloping quality that characterises tonal painting. #642E19 delivers the chromatic peak at only 7.5% - a small shot of colour with outsized visual impact. The full value range is 75 units: broad enough to build convincing three-dimensional form. The palette is recognisably John Closterman's own: particular in its temperature, chroma, and the economy of its brightest note.
