The value structure of Japonism is mid-key: quiet, controlled, and cohesive. The palette orchestrates warmth above all else - reds, ambers, and siennas take the lead. Saturation is deliberately withheld - the beauty here lies in the near-monochromatic gradations rather than colour difference. Only 4.0% is devoted to #A7452A, yet that small allocation delivers the palette's entire chromatic tension. At 51 units across the value scale, the palette keeps contrast readable without letting it dominate.
