Jean-Baptiste Robie distributes its values across the middle register, creating harmony without high contrast. Temperature is balanced: the palette pits warm earth against cool sky without declaring a winner. 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 - #E8C120 - appears at just 2.5%, deployed as a precision accent against the quieter ground. A value spread of 73 units gives the palette both depth and air - shadows are genuinely dark, lights genuinely light. Together these qualities point to the open-air Impressionist method: recording light rather than local colour. The palette is recognisably Jean-Baptiste Robie's own: particular in its temperature, chroma, and the economy of its brightest note.
