Colour circle 

"Colour Circle" is a vibrant abstract work by German Expressionist artist August Macke, known for his contributions to the Die Brücke movement. The artwork's striking geometric composition is comprised of bold blocks of color, primarily in blue, red, green, yellow, and black. The arrangement of shapes and colors evokes a sense of dynamism and harmony, reflecting Macke's exploration of form and color in his mature artistic style. Though the artwork is undated, it is likely from the period leading up to World War I, as the artist tragically died in 1914.
