The value structure of John Marin is mid-key: quiet, controlled, and cohesive. Blues and teal-greys govern the palette, lending it an aquatic or atmospheric quality. Chroma hovers near zero; colour declares itself through subtle shifts in hue rather than outright saturation. The dominant colour, #A89B88, takes 27.1% of the total area, establishing the overall mood before any other hue is introduced. Only 1.8% is devoted to #A59A63, yet that small allocation delivers the palette's entire chromatic tension. At 50 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. Palette 5 sits within the larger chromatic argument that John Marin's complete body of work advances.
