The value structure of John Trumbull is mid-key: quiet, controlled, and cohesive. The dominant temperature is warm, with earth tones and fire-hues setting the emotional key. All colours lean toward grey, building depth through value rather than colour punch. The most saturated colour, #202630, is reserved to 3.9% of the surface, where it acts as a focal punctuation. At 64 units of value range, the palette has the tonal breadth to sustain complex spatial readings. John Trumbull arrived at this balance through long practice; the palette carries the weight of that experience.
