Utagawa Toyokuni II is high in key: pale, luminous, and filled with optical air. Cool tones set the register here - the blues and greens easily outweigh any warm accents. Chroma is kept low across all colours, producing the soft, enveloping quality that characterises tonal painting. The highest-chroma note - #B09B7F - appears at just 9.2%, deployed as a precision accent against the quieter ground. The value range of 52 units sits in the comfortable middle: enough depth, enough light, neither extreme. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source. In the context of Utagawa Toyokuni II's full range of palettes, group 3 represents one movement in an ongoing chromatic dialogue.
