Nihonga is strongly light-biased - shadow is suggested rather than declared. Cool hues prevail: blues, greens, and greys anchor the palette's emotional temperature. Saturation is deliberately withheld - the beauty here lies in the near-monochromatic gradations rather than colour difference. At 9.8%, #AED5C0 carries the palette's sharpest chromatic charge: an accent that earns its place precisely because it is withheld. 75 units of value range underpin the palette's structural clarity: the eye always knows where light falls. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source.
