Values in Japonism tilt decisively toward white, giving the palette its luminous character. Cool tones set the register here - the blues and greens easily outweigh any warm accents. Muted throughout, the palette achieves its effects through value and temperature rather than chromatic force. #9BA868 delivers the chromatic peak at only 10.7% - a small shot of colour with outsized visual impact. The value range of 54 units sits in the comfortable middle: enough depth, enough light, neither extreme. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source.
