Marie-Guillemine Benoist distributes its values across the middle register, creating harmony without high contrast. Cool hues prevail: blues, greens, and greys anchor the palette's emotional temperature. Saturation is deliberately withheld - the beauty here lies in the near-monochromatic gradations rather than colour difference. The highest-chroma note - #735736 - appears at just 8.1%, deployed as a precision accent against the quieter ground. The full value range is 59 units: broad enough to build convincing three-dimensional form. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source. These proportions encode Marie-Guillemine Benoist's instinctive sense of how much of each quality the eye can hold.
