Theo van Rysselberghe is high-key - luminous, open, and weighted toward light. Theo van Rysselberghe orchestrates warmth above all else - reds, ambers, and siennas take the lead. All colours lean toward grey, building depth through value rather than colour punch. #5C392B delivers the chromatic peak at only 7.4% - a small shot of colour with outsized visual impact. The full value range is 61 units: broad enough to build convincing three-dimensional form. Theo van Rysselberghe's palette 4 carries its own internal logic while remaining in conversation with the artist's broader colour intelligence.
