Guercino sits in the centre of the value range, lending the palette a sense of even, sustained light. Guercino keeps warm and cool in parity, a balance that lends the work a perceptual shimmer. Chroma hovers near zero; colour declares itself through subtle shifts in hue rather than outright saturation. #A94C2E functions as the palette's exclamation mark: highest chroma, lowest percentage (6.5%). The full value range is 63 units: broad enough to build convincing three-dimensional form. In the context of Guercino's full range of palettes, group 1 represents one movement in an ongoing chromatic dialogue.
