Willem van Aelst sits in the centre of the value range, lending the palette a sense of even, sustained light. Cool tones set the register here - the blues and greens easily outweigh any warm accents. Chroma hovers near zero; colour declares itself through subtle shifts in hue rather than outright saturation. #393A3A claims 40.9% of the surface, functioning as the work's tonal foundation. The highest-chroma note - #AD8658 - appears at just 2.0%, deployed as a precision accent against the quieter ground. The palette spans 49 value units: a measured range that delivers coherence over drama. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. Willem van Aelst's palette 3 carries its own internal logic while remaining in conversation with the artist's broader colour intelligence.
