Marianne North is high in key: pale, luminous, and filled with optical air. Cool hues prevail: blues, greens, and greys anchor the palette's emotional temperature. The absence of saturated colour is itself an expressive choice: this is a palette of restraint and atmosphere. The most saturated colour, #9FAAC6, is reserved to 6.7% of the surface, where it acts as a focal punctuation. At 54 units across the value scale, the palette keeps contrast readable without letting it dominate. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively. In the context of Marianne North's full range of palettes, group 3 represents one movement in an ongoing chromatic dialogue.
