T?sh?sai Sharaku is high in key: pale, luminous, and filled with optical air. Temperature reads distinctly warm: the reds and earth tones from T?sh?sai Sharaku carry the compositional weight. Saturation is deliberately withheld - the beauty here lies in the near-monochromatic gradations rather than colour difference. The most saturated colour, #79504B, is reserved to 6.0% of the surface, where it acts as a focal punctuation. 47 units of value spread create a palette that is varied but unified - contrast in the service of harmony. This is palette 4 of T?sh?sai Sharaku's sequence - a single chapter in a chromatic story told across many works.
