In the painting "Woman with a Parasol – Madame Monet and Her Son" by Claude Monet, the artist successfully employs various techniques such as different brushstrokes to create texture and uses proportion to portray the figures accurately. Monet is also known for his use of cool colors to convey mood, but he predominantly uses a vibrant and warm color palette in this piece.
Therefore, the correct response to the question is:
use warm colors to create anxiety.
This statement is not applicable to Monet's work in this image, as the warm colors he uses in this painting do not convey anxiety but rather a sense of lightness and warmth.
