Keisai Eisen is high in key: pale, luminous, and filled with optical air. Temperature is cool-dominant, with blue and green families claiming the largest areas. Chroma hovers near zero; colour declares itself through subtle shifts in hue rather than outright saturation. Only 2.1% is devoted to #5D7A8E, yet that small allocation delivers the palette's entire chromatic tension. From deepest dark to palest light, the palette traverses 68 units of the value scale - a span that creates natural depth. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively. Keisai Eisen's palette 3 carries its own internal logic while remaining in conversation with the artist's broader colour intelligence.
