Willem Cornelisz Duyster works almost entirely in the lower half of the value scale, privileging depth over brilliance. Willem Cornelisz Duyster 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, #9F803E, is reserved to 3.1% of the surface, where it acts as a focal punctuation. At 58 units of value range, the palette has the tonal breadth to sustain complex spatial readings. The combination of low values, muted chroma, and compressed range is the signature of the Tonalist mode - painting as atmosphere. This is palette 4 of Willem Cornelisz Duyster's sequence - a single chapter in a chromatic story told across many works.
