Marie Duhem is high-key - luminous, open, and weighted toward light. Cool hues prevail: blues, greens, and greys anchor the palette's emotional temperature. All colours lean toward grey, building depth through value rather than colour punch. The dominant colour, #C1CED1, takes 32.7% of the total area, establishing the overall mood before any other hue is introduced. The most saturated colour, #B2914B, is reserved to 5.6% of the surface, where it acts as a focal punctuation. 32 units of value spread create a palette that is varied but unified - contrast in the service of harmony. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source. Marie Duhem's palette 1 carries its own internal logic while remaining in conversation with the artist's broader colour intelligence.
