Willem Danielsz van Tetrode keeps values measured and balanced, a hallmark of tonal restraint. Willem Danielsz van Tetrode builds on cool foundations: the palette favours the blue-cyan-green arc. Saturation is deliberately withheld - the beauty here lies in the near-monochromatic gradations rather than colour difference. Willem Danielsz van Tetrode gives 26.2% of the composition to a single #A3B3BF - a decisive chromatic anchor. At 4.0%, #5A443C carries the palette's sharpest chromatic charge: an accent that earns its place precisely because it is withheld. A value spread of 70 units gives the palette both depth and air - shadows are genuinely dark, lights genuinely light. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source. This is palette 1 of Willem Danielsz van Tetrode's sequence - a single chapter in a chromatic story told across many works.
