Marie-Denise Villers distributes its values across the middle register, creating harmony without high contrast. Warm and cool are kept in productive tension, creating the kind of chromatic harmony that sustains the eye. Saturation is deliberately withheld - the beauty here lies in the near-monochromatic gradations rather than colour difference. #4F2B0E delivers the chromatic peak at only 3.3% - a small shot of colour with outsized visual impact. The full value range is 61 units: broad enough to build convincing three-dimensional form. This is the light Marie-Denise Villers preferred, made measurable.
