Matisse wanted color to reflect feelings, and so used "nonrepresentational colors." He and the Fauves freed color from realistic representation of the subject. All the others are more traditional and realistic in their use of color.

Frida Kahlo was a Mexican artist who took up painting after a horrific bus accident at the age of eighteen in 1925 and her marriage to the European-trained muralist Diego Rivera. Kahlo painted almost entirely self portraits, typically close ups of her own face, to which she added in the background indigenous native imagery, surrealist symbols, and references to her own troubled life. Her stormy marriage to Rivera was well known, and combined with her ill health contributed to a sense of loneliness and alienation in her work.

She Wolf and Stenographic Figure are popular Pollock pieces that hint at the artist's future abandonment of representational art in favor of his classic drip paintings. The rest are other 19th/20th century artists with signature styles.

The False Mirror depicts a large eye with an iris of blue sky. The title was given to Magritte by the Belgian writer Paul Nouge. It suggests an inherent limitation in the human eye's ability to perceive truth.

Fluxus artists railed against commercial art. They wanted to shock the viewer with simple, rather than complex, work, and they were eager to work with whatever materials they had on hand rather than outsourcing anything.

Georges Braque was one of the early developers and founders of Cubism in the early twentieth century. Compared with his contemporaries Pablo Picasso and Juan Gris, Braque’s work was much more geometric and used more dull and dark colors. Still, Braque’s deconstruction of representational forms into component shapes and a modernist approach are hallmarks of cubism.

George Braque and Pablo Picasso developed cubism literally side by side, often painting in close proximity in the years 1909-1914. Built off of previous artistic movements which drew away from strict representation like expressionism and fauvism, Braque and Picasso built cubism on a structure of more monochromatic colors and geometric shapes. These approaches made their painting even less representational than previous abstract movements, while also needing more artistic and technical skill to create their works.

This painting is in the cubist style, which can be detected in the use of disjoint geometric shapes that depict the subject from multiple angles at the same time. Since Cubism is an exclusively 20th century movement, that's what the answer must be.

This is a self-portrait of Van Gogh. You can recognize his characteristic large brush strokes and post-impressionist aesthetic.

Pop Art's central tenet was that art could borrow from all sources of society including elements of high art and low or popular culture. Pop Artists believed that everything was interconnected and aimed to draw sources of their inspiration from this idea.
