Sonia Delaunay is high-key - luminous, open, and weighted toward light. Warm and cool tones are held in careful balance - neither family dominates, creating tension and resolution simultaneously. Saturation is deliberately withheld - the beauty here lies in the near-monochromatic gradations rather than colour difference. #E9E7E7 at 35.5% of the palette: an overwhelming presence that pulls all other colours into its gravitational field. Only 7.2% is devoted to #BD441E, yet that small allocation delivers the palette's entire chromatic tension. The full value range is 61 units: broad enough to build convincing three-dimensional form. Sonia Delaunay's palette 1 carries its own internal logic while remaining in conversation with the artist's broader colour intelligence.
