Low-key values are the structural spine of Giorgione, giving it gravity and atmosphere. Warmth dominates - the palette of Giorgione leans heavily on the yellow-orange-red arc of the colour wheel. Chroma hovers near zero; colour declares itself through subtle shifts in hue rather than outright saturation. 27.5% of the palette belongs to #120B0C, a concentration that makes it the unmistakable visual centre. #AA7543 functions as the palette's exclamation mark: highest chroma, lowest percentage (6.0%). The full value range is 60 units: broad enough to build convincing three-dimensional form. The combination of low values, muted chroma, and compressed range is the signature of the Tonalist mode - painting as atmosphere. In the context of Giorgione's full range of palettes, group 9 represents one movement in an ongoing chromatic dialogue.
