Yellow-Red-Blue was created by Wassily Kandinsky in 1925. The primary colors on the painting feature squares, circles and triangles and there are abstract shapes mixed in with these. There are also straight and curved black lines that go through the colors and shapes. This is to help provoke deep thought in the person viewing the piece.
This simple visual identification of forms and the main coloured masses present on the canvas is only a first approach to the inner reality of the work, whose appreciation necessitates deeper observation – not only of forms and colours involved in the painting but their relationship, their absolute and relative positions on the canvas and their harmony.
In 1925, Kandinsky taught the basic design class for beginners and the course on advanced theory at the Bauhaus. He also conducted painting classes and a workshop in which he augmented his colour theory with new elements of form psychology.
