William-Adolphe Bouguereau sits in the centre of the value range, lending the palette a sense of even, sustained light. William-Adolphe Bouguereau tilts toward cool - blues and silver-greys carry the structural weight. Every colour is desaturated; the palette proceeds through near-neutrals and gently-coloured greys. The saturated accent, #8A7347, registers at 7.0% - sparse enough to feel like a deliberate surprise. A value spread of 62 units gives the palette both depth and air - shadows are genuinely dark, lights genuinely light. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source. This is palette 9 of William-Adolphe Bouguereau's sequence - a single chapter in a chromatic story told across many works.
