Values in Paul Jacoulet rest in the mid-range - neither dramatically lit nor steeped in shadow. Cool hues prevail: blues, greens, and greys anchor the palette's emotional temperature. Chroma is held at a comfortable level - distinct colours, but no single hue is allowed to overwhelm. Rather than a studied accent, #CF6237 takes 10.8% - a bold allocation that saturates the composition's atmosphere. The full value range is 63 units: broad enough to build convincing three-dimensional form. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source. Palette 12 sits within the larger chromatic argument that Paul Jacoulet's complete body of work advances.
