Mid-key values give Utagawa Toyokuni its characteristic quietness - nothing blazes, nothing disappears. Blues and teal-greys govern the palette, lending it an aquatic or atmospheric quality. Every colour is desaturated; the palette proceeds through near-neutrals and gently-coloured greys. #9E5F52 delivers the chromatic peak at only 5.5% - a small shot of colour with outsized visual impact. The value range spans 63 units across the palette, providing the full gamut from deep shadow to near-white and ensuring clear tonal hierarchy. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. This is the light Utagawa Toyokuni preferred, made measurable.
