Limbourg brothers is high in key: pale, luminous, and filled with optical air. Temperature is cool-dominant, with blue and green families claiming the largest areas. Every colour is desaturated; the palette proceeds through near-neutrals and gently-coloured greys. 26.3% of the palette belongs to #DDD8C9, a concentration that makes it the unmistakable visual centre. Only 3.0% is devoted to #3D5198, yet that small allocation delivers the palette's entire chromatic tension. At 52 units across the value scale, the palette keeps contrast readable without letting it dominate. 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 Limbourg brothers's full range of palettes, group 4 represents one movement in an ongoing chromatic dialogue.
