The value structure of John Trumbull is mid-key: quiet, controlled, and cohesive. Temperature reads distinctly warm: the reds and earth tones from John Trumbull carry the compositional weight. Every colour is desaturated; the palette proceeds through near-neutrals and gently-coloured greys. John Trumbull gives 31.0% of the composition to a single #241F1B - a decisive chromatic anchor. At 3.5%, #B27D5E carries the palette's sharpest chromatic charge: an accent that earns its place precisely because it is withheld. The value range spans 61 units across the palette, providing the full gamut from deep shadow to near-white and ensuring clear tonal hierarchy. This is palette 4 of John Trumbull's sequence - a single chapter in a chromatic story told across many works.
