Darkness anchors Clément-Auguste Andrieux; light is rationed, creating dramatic contrast rather than open air. 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. #423A2C functions as the palette's exclamation mark: highest chroma, lowest percentage (14.5%). Spanning 53 units on the value axis, the palette achieves the balance between tonal flatness and fragmentation. This tonal restraint is characteristic of the Clément-Auguste Andrieux approach: colour serves light, not the reverse. This is palette 5 of Clément-Auguste Andrieux's sequence - a single chapter in a chromatic story told across many works.
