Gustave Bourgain works in the upper reaches of the value scale, creating an atmosphere of brightness and expansiveness. A distinctly cool atmosphere runs through this palette: sky, water, and mist given colour form. Mid-saturation across the board: the palette has colour character without chromatic excess. #C5B081 functions as the palette's exclamation mark: highest chroma, lowest percentage (11.3%). Value range is moderate at 47 units - enough contrast for legibility, not so much as to fragment the tonal unity. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. Gustave Bourgain's palette 2 carries its own internal logic while remaining in conversation with the artist's broader colour intelligence.
