Portrait of Marevna 

Diego Rivera's "Portrait of Marevna" is a Cubist painting that emphasizes geometric shapes and fragmented forms to depict the subject. The painting's bold colors, including deep browns, vibrant greens, and striking yellows, create a dynamic composition. Rivera's use of Cubism, with its focus on breaking down objects into geometric shapes and reassembling them in an abstract manner, is evident in this artwork, especially in the figure of Marevna, a Russian artist and model who was Rivera's companion.
