pastorale is high in key: pale, luminous, and filled with optical air. Cool tones set the register here - the blues and greens easily outweigh any warm accents. Chroma is held at a comfortable level - distinct colours, but no single hue is allowed to overwhelm. The highest-chroma note - #E2AF2E - appears at just 7.3%, deployed as a precision accent against the quieter ground. The full value range is 55 units: broad enough to build convincing three-dimensional form. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky.
