Light floods Ukiyo-e; the palette keeps values pale and airy across its range. Built on cool foundations: the palette favours the blue-cyan-green arc. Every colour is desaturated; the palette proceeds through near-neutrals and gently-coloured greys. #C9B59A delivers the chromatic peak at only 12.5% - a small shot of colour with outsized visual impact. A value spread of 65 units gives the palette both depth and air - shadows are genuinely dark, lights genuinely light. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source.
