Light floods Sophie Taeuber-Arp; the palette keeps values pale and airy across its range. A distinctly cool atmosphere runs through this palette: sky, water, and mist given colour form. Muted throughout, the palette achieves its effects through value and temperature rather than chromatic force. #F6EDDF claims 41.1% of the surface, functioning as the work's tonal foundation. At 0.9%, #11206F carries the palette's sharpest chromatic charge: an accent that earns its place precisely because it is withheld. The full value range is 71 units: broad enough to build convincing three-dimensional form. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. Sophie Taeuber-Arp's palette 4 carries its own internal logic while remaining in conversation with the artist's broader colour intelligence.
