Low-key values are the structural spine of Thomas Lawrence, giving it gravity and atmosphere. Thomas Lawrence tilts toward cool - blues and silver-greys carry the structural weight. Saturation is deliberately withheld - the beauty here lies in the near-monochromatic gradations rather than colour difference. 27.3% of the palette belongs to #1E1C14, a concentration that makes it the unmistakable visual centre. At 3.5%, #C99F62 carries the palette's sharpest chromatic charge: an accent that earns its place precisely because it is withheld. At 67 units of value range, the palette has the tonal breadth to sustain complex spatial readings. This tonal restraint is characteristic of the Thomas Lawrence approach: colour serves light, not the reverse. Palette 10 sits within the larger chromatic argument that Thomas Lawrence's complete body of work advances.
