Mid-key values give Naïve Art its characteristic quietness - nothing blazes, nothing disappears. Blues and teal-greys govern the palette, lending it an aquatic or atmospheric quality. Chroma hovers near zero; colour declares itself through subtle shifts in hue rather than outright saturation. The highest-chroma note - #C7A055 - appears at just 2.5%, deployed as a precision accent against the quieter ground. The full value range is 63 units: broad enough to build convincing three-dimensional form. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source.
