Joseph Anton Koch occupies the comfortable middle of the value scale, avoiding both extremes to hold the eye in a sustained middle grey. Blues and teal-greys govern the palette, lending it an aquatic or atmospheric quality. Saturation is deliberately withheld - the beauty here lies in the near-monochromatic gradations rather than colour difference. The highest-chroma note - #8A7258 - appears at just 6.5%, deployed as a precision accent against the quieter ground. The value range spans 60 units across the palette, providing the full gamut from deep shadow to near-white and ensuring clear tonal hierarchy. 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 Joseph Anton Koch's full range of palettes, group 2 represents one movement in an ongoing chromatic dialogue.
