Henri Rousseau sits in the centre of the value range, lending the palette a sense of even, sustained light. Blues and teal-greys govern the palette, lending it an aquatic or atmospheric quality. Muted throughout, the palette achieves its effects through value and temperature rather than chromatic force. The highest-chroma note - #A77D5A - appears at just 2.7%, deployed as a precision accent against the quieter ground. At 65 units of value range, the palette has the tonal breadth to sustain complex spatial readings. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. Henri Rousseau's palette 4 carries its own internal logic while remaining in conversation with the artist's broader colour intelligence.
