John Duncan is high in key: pale, luminous, and filled with optical air. Warmth dominates - the palette of John Duncan leans heavily on the yellow-orange-red arc of the colour wheel. Saturation is deliberately withheld - the beauty here lies in the near-monochromatic gradations rather than colour difference. #6A4B32 functions as the palette's exclamation mark: highest chroma, lowest percentage (9.0%). At 59 units of value range, the palette has the tonal breadth to sustain complex spatial readings. John Duncan's palette 3 carries its own internal logic while remaining in conversation with the artist's broader colour intelligence.
