Mid-key values give Sophie Taeuber-Arp its characteristic quietness - nothing blazes, nothing disappears. Sophie Taeuber-Arp tilts toward cool - blues and silver-greys carry the structural weight. Chroma is moderate: colours carry enough saturation to be read as colour, but the palette stops well short of garish intensity. #253178 functions as the palette's exclamation mark: highest chroma, lowest percentage (6.7%). A value spread of 64 units gives the palette both depth and air - shadows are genuinely dark, lights genuinely light. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. Sophie Taeuber-Arp arrived at this balance through long practice; the palette carries the weight of that experience.
