The value structure of Jan Sluyters is mid-key: quiet, controlled, and cohesive. Jan Sluyters 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. A single dominant - #140E07 at 30.8% - sets the character of the whole composition. The most saturated colour, #CC8E70, is reserved to 2.9% of the surface, where it acts as a focal punctuation. Spanning 53 units on the value axis, the palette achieves the balance between tonal flatness and fragmentation. Palette 5 sits within the larger chromatic argument that Jan Sluyters's complete body of work advances.
