Xul Solar 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. Xul Solar gives 40.1% of the composition to a single #457BCF - a decisive chromatic anchor. #7A2E22 delivers the chromatic peak at only 4.5% - a small shot of colour with outsized visual impact. The value range spans 70 units across the palette, providing the full gamut from deep shadow to near-white and ensuring clear tonal hierarchy. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. Palette 3 sits within the larger chromatic argument that Xul Solar's complete body of work advances.
