Tsukioka Yoshitoshi distributes its values across the middle register, creating harmony without high contrast. Blues and teal-greys govern the palette, lending it an aquatic or atmospheric quality. All colours lean toward grey, building depth through value rather than colour punch. The most saturated colour, #AE5865, is reserved to 2.4% of the surface, where it acts as a focal punctuation. The full value range is 60 units: broad enough to build convincing three-dimensional form. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source. This is palette 6 of Tsukioka Yoshitoshi's sequence - a single chapter in a chromatic story told across many works.
