Charles Victor Thirion sits in the centre of the value range, lending the palette a sense of even, sustained light. 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. The highest-chroma note - #9A6944 - appears at just 7.5%, deployed as a precision accent against the quieter ground. The value range spans 73 units across the palette, providing the full gamut from deep shadow to near-white and ensuring clear tonal hierarchy. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. This is the light Charles Victor Thirion preferred, made measurable.
