Jacques d'Arthois occupies the comfortable middle of the value scale, avoiding both extremes to hold the eye in a sustained middle grey. Blues and teal-greys govern the palette, lending it an aquatic or atmospheric quality. Muted throughout, the palette achieves its effects through value and temperature rather than chromatic force. Jacques d'Arthois gives 27.5% of the composition to a single #251E13 - a decisive chromatic anchor. #BC9865 delivers the chromatic peak at only 4.9% - a small shot of colour with outsized visual impact. The palette spans 46 value units: a measured range that delivers coherence over drama. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively. Jacques d'Arthois's palette 5 carries its own internal logic while remaining in conversation with the artist's broader colour intelligence.
