Marianne North occupies the comfortable middle of the value scale, avoiding both extremes to hold the eye in a sustained middle grey. Cool hues prevail: blues, greens, and greys anchor the palette's emotional temperature. Every colour is desaturated; the palette proceeds through near-neutrals and gently-coloured greys. #735135 delivers the chromatic peak at only 5.7% - a small shot of colour with outsized visual impact. Value range is moderate at 49 units - enough contrast for legibility, not so much as to fragment the tonal unity. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source. Marianne North arrived at this balance through long practice; the palette carries the weight of that experience.
