Darkness anchors Jules-Alexandre Grun; light is rationed, creating dramatic contrast rather than open air. Neither warm nor cool has the upper hand here; the equilibrium between the two generates the palette's visual energy. Chroma is kept low across all colours, producing the soft, enveloping quality that characterises tonal painting. The most saturated colour, #9B7F53, is reserved to 3.0% of the surface, where it acts as a focal punctuation. At 41 units across the value scale, the palette keeps contrast readable without letting it dominate. The combination of low values, muted chroma, and compressed range is the signature of the Tonalist mode - painting as atmosphere. Jules-Alexandre Grun's palette 6 carries its own internal logic while remaining in conversation with the artist's broader colour intelligence.
