Mid-key values give Theodoor van Thulden its characteristic quietness - nothing blazes, nothing disappears. The dominant temperature is warm, with earth tones and fire-hues setting the emotional key. Saturation is deliberately withheld - the beauty here lies in the near-monochromatic gradations rather than colour difference. At 4.2%, #A54332 carries the palette's sharpest chromatic charge: an accent that earns its place precisely because it is withheld. The full value range is 68 units: broad enough to build convincing three-dimensional form. This is palette 3 of Theodoor van Thulden's sequence - a single chapter in a chromatic story told across many works.
