The value structure of Louis Janmot is mid-key: quiet, controlled, and cohesive. Yellow, ochre, sienna: warm hues that Louis Janmot deploys as the palette's primary energy. Chroma is held at a comfortable level - distinct colours, but no single hue is allowed to overwhelm. The saturated accent, #803B1A, registers at 8.5% - sparse enough to feel like a deliberate surprise. 55 units of value range underpin the palette's structural clarity: the eye always knows where light falls. Louis Janmot's palette 4 carries its own internal logic while remaining in conversation with the artist's broader colour intelligence.
