Final answer:
Wanda Gág's paintings are known for their symbolism, use of partial body parts, and a vivid display of colors to evoke emotional experiences. She was innovative in her materials, using traditional oil paints and newer mediums like Plexiglas and synthetic resin.
Step-by-step explanation:
Wanda Gág frequently incorporated symbolism, partial body parts, and imaginative elements into her paintings. This significance is seen in her work such as Portrait Fragment (6.6.20), where her face is depicted in a slightly distorted, fragmented style with linear waves, and she skillfully uses contrasting colors to draw focus to her eyes. Gág's experimentation with mediums, switching from traditional canvas to plastic sheets and Plexiglas, and her use of traditional oil paints alongside auto enamel and synthetic resin, shows her innovative spirit and desire to express intricate emotional experiences in her art. Furthermore, in other paintings like White Flower (6.8.12), Agnes Martin prompts a mental interaction with her artwork, rather than a literal one, showing her focus on the viewer's emotional and psychological engagement with her art.
