The value structure of John Quidor is mid-key: quiet, controlled, and cohesive. The dominant temperature is warm, with earth tones and fire-hues setting the emotional key. The absence of saturated colour is itself an expressive choice: this is a palette of restraint and atmosphere. The saturated accent, #705B19, registers at 8.0% - sparse enough to feel like a deliberate surprise. The palette spans 51 value units: a measured range that delivers coherence over drama. This is palette 4 of John Quidor's sequence - a single chapter in a chromatic story told across many works.
