Darkness anchors Charles Cottet; light is rationed, creating dramatic contrast rather than open air. Charles Cottet builds on cool foundations: the palette favours the blue-cyan-green arc. Chroma is kept low across all colours, producing the soft, enveloping quality that characterises tonal painting. #0F110C claims 31.0% of the surface, functioning as the work's tonal foundation. The saturated accent, #4E311F, registers at 3.9% - sparse enough to feel like a deliberate surprise. The value range spans 58 units across the palette, providing the full gamut from deep shadow to near-white and ensuring clear tonal hierarchy. The combination of low values, muted chroma, and compressed range is the signature of the Tonalist mode - painting as atmosphere. Charles Cottet's palette 5 carries its own internal logic while remaining in conversation with the artist's broader colour intelligence.
