The value structure of Constant Permeke is mid-key: quiet, controlled, and cohesive. Constant Permeke builds on cool foundations: the palette favours the blue-cyan-green arc. Chroma is kept low across all colours, producing the soft, enveloping quality that characterises tonal painting. At 3.1%, #B6A582 carries the palette's sharpest chromatic charge: an accent that earns its place precisely because it is withheld. At 39 units across the value scale, the palette keeps contrast readable without letting it dominate. 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 Constant Permeke's full range of palettes, group 3 represents one movement in an ongoing chromatic dialogue.
