Values in Thomas Dewing rest in the mid-range - neither dramatically lit nor steeped in shadow. Blues and teal-greys govern the palette, lending it an aquatic or atmospheric quality. Chroma is held at a comfortable level - distinct colours, but no single hue is allowed to overwhelm. The saturated accent, #A1783F, registers at 8.7% - sparse enough to feel like a deliberate surprise. A value spread of 58 units gives the palette both depth and air - shadows are genuinely dark, lights genuinely light. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. The palette is recognisably Thomas Dewing's own: particular in its temperature, chroma, and the economy of its brightest note.
