Light floods Léon-Victor Dupré; the palette keeps values pale and airy across its range. Léon-Victor Dupré tilts toward cool - blues and silver-greys carry the structural weight. Chroma is moderate: colours carry enough saturation to be read as colour, but the palette stops well short of garish intensity. Léon-Victor Dupré gives 26.8% of the composition to a single #DCD19B - a decisive chromatic anchor. Only 3.9% is devoted to #C1B45C, yet that small allocation delivers the palette's entire chromatic tension. Spanning 50 units on the value axis, the palette achieves the balance between tonal flatness and fragmentation. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source. Palette 1 sits within the larger chromatic argument that Léon-Victor Dupré's complete body of work advances.
