Pierre Roy is strongly light-biased - shadow is suggested rather than declared. Pierre Roy tilts toward cool - blues and silver-greys carry the structural weight. Mid-saturation across the board: the palette has colour character without chromatic excess. The most saturated colour, #BDA63A, is reserved to 12.1% of the surface, where it acts as a focal punctuation. From deepest dark to palest light, the palette traverses 57 units of the value scale - a span that creates natural depth. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source. Pierre Roy's palette 1 carries its own internal logic while remaining in conversation with the artist's broader colour intelligence.
