At Bauhaus, the lyrical abstraction of Kandinsky's early work was transformed into a more rational geometric language, which the painter described as his "cold period." Produced in 1925, the same year in which Kandinsky wrote his treatise Point and Line to Plane, Gelb-Rot-Blau represents a stylistic turning point. The line bends and there are gradations of color again. This basis of this painting lies in the balance between contradictory and complementary elements. To the left are geometric lines and luminous colors. To the right are sinuous forms and dark hues. The main emphasis is on the three primary colors, which form the basis of Kandinsky's studies and articulate the composition around two centers.
