The colour logic of Ukiyo-e is concentrated here: its characteristic value range, temperature bias, and chroma level. Ukiyo-e is strongly light-biased - shadow is suggested rather than declared. Temperature is cool-dominant, with blue and green families claiming the largest areas. Muted throughout, the palette achieves its effects through value and temperature rather than chromatic force. #C39C6F functions as the palette's exclamation mark: highest chroma, lowest percentage (7.3%). The value range spans 62 units across the palette, providing the full gamut from deep shadow to near-white and ensuring clear tonal hierarchy. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source. Applied to contemporary work, these proportions immediately evoke the Ukiyo-e register.
