Abstract Composition in Red, Brown, Black, Blue, and White 

This abstract watercolor painting by Mark Rothko showcases his early exploration of abstract forms and color. The piece, likely created before his signature "color field" paintings, features bold geometric shapes in red, brown, black, blue, and white, suggesting the influence of Cubism. Rothko's later work would move away from these hard-edged forms, but his early abstractions are still notable for their experimental nature and expressionist qualities.
