Kathe Kollwitz is high in key: pale, luminous, and filled with optical air. Cool hues prevail: blues, greens, and greys anchor the palette's emotional temperature. Chroma is kept low across all colours, producing the soft, enveloping quality that characterises tonal painting. The highest-chroma note - #202618 - appears at just 10.5%, deployed as a precision accent against the quieter ground. The full value range is 69 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. In the context of Kathe Kollwitz's full range of palettes, group 3 represents one movement in an ongoing chromatic dialogue.
