The high-key values of Japonism give it an effulgent, almost bleached quality. Temperature is balanced: the palette pits warm earth against cool sky without declaring a winner. Mid-saturation across the board: the palette has colour character without chromatic excess. The most saturated colour, #A8673F, covers 3.0% of the surface: too much to call an accent, too strong to ignore. At 54 units across the value scale, the palette keeps contrast readable without letting it dominate. Together these qualities point to the open-air Impressionist method: recording light rather than local colour.
