Guercino is built on dark foundations, with values clustered toward shadow. Warm and cool tones are held in careful balance - neither family dominates, creating tension and resolution simultaneously. Chroma hovers near zero; colour declares itself through subtle shifts in hue rather than outright saturation. 38.0% of the palette belongs to #242128, a concentration that makes it the unmistakable visual centre. #C99162 functions as the palette's exclamation mark: highest chroma, lowest percentage (2.6%). The full value range is 66 units: broad enough to build convincing three-dimensional form. This tonal restraint is characteristic of the Guercino approach: colour serves light, not the reverse. In the context of Guercino's full range of palettes, group 6 represents one movement in an ongoing chromatic dialogue.
