Gustave Boulanger keeps values measured and balanced, a hallmark of tonal restraint. Heat pervades this palette; warm chromatic identities outweigh cool ones at almost every weight. Mid-saturation across the board: the palette has colour character without chromatic excess. The most saturated colour, #E0C8AB, is reserved to 4.8% of the surface, where it acts as a focal punctuation. At 61 units of value range, the palette has the tonal breadth to sustain complex spatial readings. In the context of Gustave Boulanger's full range of palettes, group 4 represents one movement in an ongoing chromatic dialogue.
