The value structure of Gustave Boulanger is mid-key: quiet, controlled, and cohesive. Temperature reads distinctly warm: the reds and earth tones from Gustave Boulanger carry the compositional weight. A restrained, mid-chroma palette: every hue is present and legible, but nothing shouts. Rather than a studied accent, #56130E takes 8.3% - a bold allocation that saturates the composition's atmosphere. The full value range is 57 units: broad enough to build convincing three-dimensional form. This is palette 1 of Gustave Boulanger's sequence - a single chapter in a chromatic story told across many works.
