The statement that the artist Claude Monet did not successfully achieve in "Woman with a Parasol – Madame Monet and Her Son" is:
use warm colors to create anxiety.
Monet's use of colors in this painting predominantly features lighter, softer tones, which do not convey a sense of anxiety. Instead, the colors are more cool and calming, aligning with the overall impressionist style that aims to capture mood and atmosphere rather than invoke anxiety.
