Keisai Eisen is high in key: pale, luminous, and filled with optical air. Keisai Eisen orchestrates warmth above all else - reds, ambers, and siennas take the lead. Every colour is desaturated; the palette proceeds through near-neutrals and gently-coloured greys. 35.6% of the palette belongs to #D5BBA8, a concentration that makes it the unmistakable visual centre. The highest-chroma note - #BB5F55 - appears at just 5.8%, deployed as a precision accent against the quieter ground. The value range of 48 units sits in the comfortable middle: enough depth, enough light, neither extreme. This is palette 7 of Keisai Eisen's sequence - a single chapter in a chromatic story told across many works.
