Theodore 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. Chroma hovers near zero; colour declares itself through subtle shifts in hue rather than outright saturation. #C3B191 functions as the palette's exclamation mark: highest chroma, lowest percentage (11.1%). 65 units of value range underpin the palette's structural clarity: the eye always knows where light falls. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source. Palette 5 sits within the larger chromatic argument that Theodore Rousseau's complete body of work advances.
