John Singleton Copley works almost entirely in the lower half of the value scale, privileging depth over brilliance. Temperature is balanced: the palette pits warm earth against cool sky without declaring a winner. Chroma hovers near zero; colour declares itself through subtle shifts in hue rather than outright saturation. John Singleton Copley gives 37.9% of the composition to a single #161616 - a decisive chromatic anchor. #D4B770 delivers the chromatic peak at only 1.6% - a small shot of colour with outsized visual impact. From deepest dark to palest light, the palette traverses 68 units of the value scale - a span that creates natural depth. This tonal restraint is characteristic of the John Singleton Copley approach: colour serves light, not the reverse. Palette 8 sits within the larger chromatic argument that John Singleton Copley's complete body of work advances.
