The value structure of Alfred Guillou is mid-key: quiet, controlled, and cohesive. Temperature is balanced: the palette pits warm earth against cool sky without declaring a winner. Chroma hovers near zero; colour declares itself through subtle shifts in hue rather than outright saturation. Only 11.1% is devoted to #463021, yet that small allocation delivers the palette's entire chromatic tension. The value range spans 59 units across the palette, providing the full gamut from deep shadow to near-white and ensuring clear tonal hierarchy. In the context of Alfred Guillou's full range of palettes, group 3 represents one movement in an ongoing chromatic dialogue.
