Mid-key values give Jean Dubuffet its characteristic quietness - nothing blazes, nothing disappears. 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. A single dominant - #272622 at 25.0% - sets the character of the whole composition. The saturated accent, #CEA875, registers at 5.0% - sparse enough to feel like a deliberate surprise. From deepest dark to palest light, the palette traverses 66 units of the value scale - a span that creates natural depth. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source. These proportions encode Jean Dubuffet's instinctive sense of how much of each quality the eye can hold.
