John Singleton Copley works almost entirely in the lower half of the value scale, privileging depth over brilliance. Temperature reads distinctly warm: the reds and earth tones from John Singleton Copley carry the compositional weight. Mid-range chroma keeps the palette grounded - colourful but not strident. #100409 at 36.9% of the palette: an overwhelming presence that pulls all other colours into its gravitational field. The saturated accent, #37090D, registers at 5.4% - sparse enough to feel like a deliberate surprise. At 66 units of value range, the palette has the tonal breadth to sustain complex spatial readings. John Singleton Copley follows the old-master formula: deep values, warm underlighting, and chroma held in reserve for the focal point. Palette 14 sits within the larger chromatic argument that John Singleton Copley's complete body of work advances.
