The value structure of Sophie Taeuber-Arp is mid-key: quiet, controlled, and cohesive. Temperature is cool-dominant, with blue and green families claiming the largest areas. Saturation is deliberately withheld - the beauty here lies in the near-monochromatic gradations rather than colour difference. #A6A8A6 claims 27.1% of the surface, functioning as the work's tonal foundation. The saturated accent, #394188, registers at 2.5% - sparse enough to feel like a deliberate surprise. A value spread of 61 units gives the palette both depth and air - shadows are genuinely dark, lights genuinely light. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively. Palette 6 sits within the larger chromatic argument that Sophie Taeuber-Arp's complete body of work advances.
