Henri de Toulouse-Lautrec is high-key - luminous, open, and weighted toward light. The palette achieves thermal balance - reds and blues, ochres and greens, each holding the other in check. Saturation is measured and controlled, giving the palette presence without visual aggression. Henri de Toulouse-Lautrec gives 31.8% of the composition to a single #E5C571 - a decisive chromatic anchor. #D25232 functions as the palette's exclamation mark: highest chroma, lowest percentage (3.8%). At 56 units of value range, the palette has the tonal breadth to sustain complex spatial readings. The combination of mid-to-high key, balanced temperature, and elevated chroma is characteristic of Impressionist observation: light broken into its component hues. Henri de Toulouse-Lautrec's palette 4 carries its own internal logic while remaining in conversation with the artist's broader colour intelligence.
