Values in Theo van Rysselberghe rest in the mid-range - neither dramatically lit nor steeped in shadow. A distinctly cool atmosphere runs through this palette: sky, water, and mist given colour form. Chroma hovers near zero; colour declares itself through subtle shifts in hue rather than outright saturation. The most saturated colour, #935E50, is reserved to 6.2% of the surface, where it acts as a focal punctuation. At 60 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 Theo van Rysselberghe's full range of palettes, group 6 represents one movement in an ongoing chromatic dialogue.
