Paul Grolleron sits in the centre of the value range, lending the palette a sense of even, sustained light. Paul Grolleron builds on cool foundations: the palette favours the blue-cyan-green arc. Saturation is deliberately withheld - the beauty here lies in the near-monochromatic gradations rather than colour difference. The most saturated colour, #4A3828, is reserved to 5.6% of the surface, where it acts as a focal punctuation. At 44 units across the value scale, the palette keeps contrast readable without letting it dominate. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source. Paul Grolleron's palette 3 carries its own internal logic while remaining in conversation with the artist's broader colour intelligence.
