Marianne North keeps values measured and balanced, a hallmark of tonal restraint. Cool tones set the register here - the blues and greens easily outweigh any warm accents. Chroma is moderate: colours carry enough saturation to be read as colour, but the palette stops well short of garish intensity. The saturated accent, #B99C6C, registers at 6.2% - sparse enough to feel like a deliberate surprise. Value range is moderate at 49 units - enough contrast for legibility, not so much as to fragment the tonal unity. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. Palette 6 sits within the larger chromatic argument that Marianne North's complete body of work advances.
