What is a significant theme in Impressionist art?

In Impressionist art, a significant theme is the exploration of light and its changing qualities. Artists associated with the Impressionist movement, such as Claude Monet and Pierre-Auguste Renoir, sought to capture the fleeting effects of light and atmosphere in their works. This approach involved painting en plein air (outdoors) and using loose brushstrokes to depict the brightness and movement of light, rather than focusing on exact details or realism. Their emphasis on how light transforms colors and shapes, especially during different times of the day or under various weather conditions, defines the essence of Impressionist painting. This theme allows viewers to experience a sense of immediacy and connection with the natural world, which is a hallmark of the movement.

The other options emphasize aspects that are generally not characteristic of Impressionism. For instance, while abstract forms and geometric shapes are often associated with later art movements, Impressionism tended to focus more on naturalistic scenes influenced by light. Similarly, focusing on symmetry runs counter to the spontaneity and dynamic quality that Impressionists embraced in their works.
