Marianne North keeps values measured and balanced, a hallmark of tonal restraint. The palette achieves thermal balance - reds and blues, ochres and greens, each holding the other in check. Saturation is deliberately withheld - the beauty here lies in the near-monochromatic gradations rather than colour difference. The saturated accent, #A7434F, registers at 4.8% - sparse enough to feel like a deliberate surprise. At 45 units across the value scale, the palette keeps contrast readable without letting it dominate. In the context of Marianne North's full range of palettes, group 10 represents one movement in an ongoing chromatic dialogue.
