Values in Jean-Baptiste Robie rest in the mid-range - neither dramatically lit nor steeped in shadow. A distinctly cool atmosphere runs through this palette: sky, water, and mist given colour form. Chroma is kept low across all colours, producing the soft, enveloping quality that characterises tonal painting. The saturated accent, #A35543, registers at 5.2% - sparse enough to feel like a deliberate surprise. 54 units of value spread create a palette that is varied but unified - contrast in the service of harmony. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. Palette 1 sits within the larger chromatic argument that Jean-Baptiste Robie's complete body of work advances.
