Henri Gervex distributes its values across the middle register, creating harmony without high contrast. Blues and teal-greys govern the palette, lending it an aquatic or atmospheric quality. Chroma is kept low across all colours, producing the soft, enveloping quality that characterises tonal painting. Only 1.4% is devoted to #C06931, yet that small allocation delivers the palette's entire chromatic tension. At 65 units of value range, the palette has the tonal breadth to sustain complex spatial readings. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source. In the context of Henri Gervex's full range of palettes, group 3 represents one movement in an ongoing chromatic dialogue.
