The value structure of Caravaggio is mid-key: quiet, controlled, and cohesive. Cool hues prevail: blues, greens, and greys anchor the palette's emotional temperature. Chroma hovers near zero; colour declares itself through subtle shifts in hue rather than outright saturation. #6B452C functions as the palette's exclamation mark: highest chroma, lowest percentage (5.8%). A value spread of 59 units gives the palette both depth and air - shadows are genuinely dark, lights genuinely light. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source. In the context of Caravaggio's full range of palettes, group 3 represents one movement in an ongoing chromatic dialogue.
