The high-key values of Outsider art give it an effulgent, almost bleached quality. Temperature is balanced: the palette pits warm earth against cool sky without declaring a winner. Chroma is held at a comfortable level - distinct colours, but no single hue is allowed to overwhelm. The most saturated colour, #E5AC24, is reserved to 10.6% of the surface, where it acts as a focal punctuation. At 53 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.
