The colour logic of Nihonga is concentrated here: its characteristic value range, temperature bias, and chroma level. Nihonga is high-key - luminous, open, and weighted toward light. Blues and teal-greys govern the palette, lending it an aquatic or atmospheric quality. Muted throughout, the palette achieves its effects through value and temperature rather than chromatic force. The highest-chroma note - #547CDC - appears at just 3.1%, deployed as a precision accent against the quieter ground. A value spread of 66 units gives the palette both depth and air - shadows are genuinely dark, lights genuinely light. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively. Any work aspiring to the Nihonga sensibility would find reliable footing in these values.
