Values in Charles Bertrand d' Entraygues rest in the mid-range - neither dramatically lit nor steeped in shadow. The palette achieves thermal balance - reds and blues, ochres and greens, each holding the other in check. Saturation is deliberately withheld - the beauty here lies in the near-monochromatic gradations rather than colour difference. The saturated accent, #983328, registers at 4.0% - sparse enough to feel like a deliberate surprise. At 73 units of value range, the palette has the tonal breadth to sustain complex spatial readings. This is the light Charles Bertrand d' Entraygues preferred, made measurable.
