The value structure of Jean-François Bosio is mid-key: quiet, controlled, and cohesive. Cool tones set the register here - the blues and greens easily outweigh any warm accents. Chroma hovers near zero; colour declares itself through subtle shifts in hue rather than outright saturation. #E3CB64 functions as the palette's exclamation mark: highest chroma, lowest percentage (2.5%). At 57 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. In the context of Jean-François Bosio's full range of palettes, group 3 represents one movement in an ongoing chromatic dialogue.
