Eustache Le Sueur 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. Chroma hovers near zero; colour declares itself through subtle shifts in hue rather than outright saturation. The saturated accent, #A7633C, registers at 3.7% - sparse enough to feel like a deliberate surprise. A value spread of 59 units gives the palette both depth and air - shadows are genuinely dark, lights genuinely light. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively. This is palette 6 of Eustache Le Sueur's sequence - a single chapter in a chromatic story told across many works.
