Rosa Bonheur 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. #625835 delivers the chromatic peak at only 10.8% - a small shot of colour with outsized visual impact. At 67 units of value range, the palette has the tonal breadth to sustain complex spatial readings. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively. This is palette 4 of Rosa Bonheur's sequence - a single chapter in a chromatic story told across many works.
