Charles-Nicolas Guillon keeps values measured and balanced, a hallmark of tonal restraint. Charles-Nicolas Guillon tilts toward cool - blues and silver-greys carry the structural weight. Saturation is deliberately withheld - the beauty here lies in the near-monochromatic gradations rather than colour difference. The saturated accent, #61321A, registers at 5.4% - sparse enough to feel like a deliberate surprise. The full value range is 64 units: broad enough to build convincing three-dimensional form. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. Palette 1 sits within the larger chromatic argument that Charles-Nicolas Guillon's complete body of work advances.
