Marianne North occupies the comfortable middle of the value scale, avoiding both extremes to hold the eye in a sustained middle grey. Temperature is cool-dominant, with blue and green families claiming the largest areas. A restrained, mid-chroma palette: every hue is present and legible, but nothing shouts. The most saturated colour, #CBBB55, is reserved to 3.8% of the surface, where it acts as a focal punctuation. Spanning 44 units on the value axis, the palette achieves the balance between tonal flatness and fragmentation. 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 Marianne North's full range of palettes, group 4 represents one movement in an ongoing chromatic dialogue.
