Rayonism occupies the comfortable middle of the value scale, avoiding both extremes to hold the eye in a sustained middle grey. The palette tilts toward cool - blues and silver-greys carry the structural weight. Chroma is held at a comfortable level - distinct colours, but no single hue is allowed to overwhelm. #B3B1C4 claims 31.0% of the surface, functioning as the work's tonal foundation. At 6.9%, #211B47 carries the palette's sharpest chromatic charge: an accent that earns its place precisely because it is withheld. Spanning 52 units on the value axis, the palette achieves the balance between tonal flatness and fragmentation. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky.
