Paul Jacoulet is high in key: pale, luminous, and filled with optical air. Blues and teal-greys govern the palette, lending it an aquatic or atmospheric quality. Chroma is moderate: colours carry enough saturation to be read as colour, but the palette stops well short of garish intensity. #CA3353 functions as the palette's exclamation mark: highest chroma, lowest percentage (7.1%). The value range spans 74 units across the palette, providing the full gamut from deep shadow to near-white and ensuring clear tonal hierarchy. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source. This is palette 2 of Paul Jacoulet's sequence - a single chapter in a chromatic story told across many works.
