Keisai Eisen is high in key: pale, luminous, and filled with optical air. A distinctly cool atmosphere runs through this palette: sky, water, and mist given colour form. Chroma hovers near zero; colour declares itself through subtle shifts in hue rather than outright saturation. Only 1.6% is devoted to #103473, yet that small allocation delivers the palette's entire chromatic tension. A value spread of 68 units gives the palette both depth and air - shadows are genuinely dark, lights genuinely light. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively. Palette 8 sits within the larger chromatic argument that Keisai Eisen's complete body of work advances.
