The value structure of Charles Olivier de Penne is mid-key: quiet, controlled, and cohesive. Cool hues prevail: blues, greens, and greys anchor the palette's emotional temperature. Muted throughout, the palette achieves its effects through value and temperature rather than chromatic force. Only 6.7% is devoted to #727341, yet that small allocation delivers the palette's entire chromatic tension. The full value range is 59 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 5 sits within the larger chromatic argument that Charles Olivier de Penne's complete body of work advances.
