Jean Dupas distributes its values across the middle register, creating harmony without high contrast. The palette achieves thermal balance - reds and blues, ochres and greens, each holding the other in check. Chroma hovers near zero; colour declares itself through subtle shifts in hue rather than outright saturation. The highest-chroma note - #AF8136 - appears at just 3.3%, deployed as a precision accent against the quieter ground. At 46 units across the value scale, the palette keeps contrast readable without letting it dominate. This is the light Jean Dupas preferred, made measurable.
