Theo van Rysselberghe keeps values measured and balanced, a hallmark of tonal restraint. Theo van Rysselberghe orchestrates warmth above all else - reds, ambers, and siennas take the lead. Chroma hovers near zero; colour declares itself through subtle shifts in hue rather than outright saturation. The most saturated colour, #DCC9B0, is reserved to 4.6% of the surface, where it acts as a focal punctuation. The value range spans 64 units across the palette, providing the full gamut from deep shadow to near-white and ensuring clear tonal hierarchy. Palette 15 sits within the larger chromatic argument that Theo van Rysselberghe's complete body of work advances.
