But the images in these paintings are not clear and difficult to distinguish. They are often only implied by some very simple lines or color blocks; Color blocks are often drawn outside the outline, which is inconsistent with the outline. Here, lines, blocks and colors themselves are obviously much more important than the story depicted. Therefore, these images are often submerged by dancing shapes and full and colorful colors. Composition No.4, an oil painting created in 19 1 1, is Kandinsky's representative work of this semi-abstract lyric painting style. All forms in this painting have arguable sources. The theme of this painting is Russian knights fighting in Shan Ye (Kandinsky is always obsessed with painting this dreamy fairy tale). In this abstract painting, we can still vaguely identify some forms: in the center of the picture is a knight with a spear fighting together; On the right is a lancer in a red hat; There is a castle in the background; Birds in the air flock; The sunshine turned into a rainbow through the drizzle.

The painter made a meaningful formal treatment here. He deliberately hides the horizon as the main line in landscape painting; The shape of the mountain enables him to break the horizon into diagonal lines. This has a direct impact on the whole picture space-not only makes the objective and quiet horizon separating heaven and earth disappear here, but also makes the painting have a complete painting space structure similar to cubist painting.

Lines and colors become independent elements in painting. Discontinuity of lines forms tension, which produces the rhythm of interaction and connection throughout the whole painting. Color expresses the shape independently, as a plane, floating in an uncertain space, separated from descriptive content. The image in the painting is no longer illuminated by some external light source: the light comes entirely from the color itself.
