Willem Kalf occupies the comfortable middle of the value scale, avoiding both extremes to hold the eye in a sustained middle grey. Warmth dominates - the palette of Willem Kalf leans heavily on the yellow-orange-red arc of the colour wheel. Chroma hovers near zero; colour declares itself through subtle shifts in hue rather than outright saturation. The most saturated colour, #A08243, is reserved to 4.9% of the surface, where it acts as a focal punctuation. Value range is moderate at 52 units - enough contrast for legibility, not so much as to fragment the tonal unity. Palette 4 sits within the larger chromatic argument that Willem Kalf's complete body of work advances.
