Light floods Gustave Bourgain; the palette keeps values pale and airy across its range. Blues and teal-greys govern the palette, lending it an aquatic or atmospheric quality. Mid-saturation across the board: the palette has colour character without chromatic excess. #8E6A2F delivers the chromatic peak at only 8.4% - a small shot of colour with outsized visual impact. 45 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 3 sits within the larger chromatic argument that Gustave Bourgain's complete body of work advances.
