Rogier van der Weyden sits in the centre of the value range, lending the palette a sense of even, sustained light. Cool hues prevail: blues, greens, and greys anchor the palette's emotional temperature. Saturation is deliberately withheld - the beauty here lies in the near-monochromatic gradations rather than colour difference. The saturated accent, #9C4335, registers at 2.1% - sparse enough to feel like a deliberate surprise. The full value range is 62 units: broad enough to build convincing three-dimensional form. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source. Rogier van der Weyden's palette 1 carries its own internal logic while remaining in conversation with the artist's broader colour intelligence.
