James Thornhill keeps values measured and balanced, a hallmark of tonal restraint. Blues and teal-greys govern the palette, lending it an aquatic or atmospheric quality. Saturation is deliberately withheld - the beauty here lies in the near-monochromatic gradations rather than colour difference. James Thornhill gives 30.6% of the composition to a single #FEFEFD - a decisive chromatic anchor. #684D2D functions as the palette's exclamation mark: highest chroma, lowest percentage (7.0%). At 72 units of value range, the palette has the tonal breadth to sustain complex spatial readings. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively. This is palette 3 of James Thornhill's sequence - a single chapter in a chromatic story told across many works.
