Mid-key values give Japonism its characteristic quietness - nothing blazes, nothing disappears. Warm and cool tones are held in careful balance - neither family dominates, creating tension and resolution simultaneously. Chroma is moderate: colours carry enough saturation to be read as colour, but the palette stops well short of garish intensity. The highest-chroma note - #312017 - appears at just 5.7%, deployed as a precision accent against the quieter ground. 44 units of value spread create a palette that is varied but unified - contrast in the service of harmony. Together these qualities point to the open-air Impressionist method: recording light rather than local colour.
