Ukiyo-e works in the upper reaches of the value scale, creating an atmosphere of brightness and expansiveness. Cool tones set the register here - the blues and greens easily outweigh any warm accents. Chroma is held at a comfortable level - distinct colours, but no single hue is allowed to overwhelm. The saturated accent, #946B55, registers at 3.9% - sparse enough to feel like a deliberate surprise. 66 units of value range underpin the palette's structural clarity: the eye always knows where light falls. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky.
