Squares with Concentric Circles perhaps Kandinsky's most recognizable work, is not actually a full-fledged picture. This drawing is a small study on how different color combinations are perceived that the painter used in his creative process as a support material.
For Kandinsky, color meant more than just a visual component of a picture. Color is its soul. In his books, he described his own perspective on how colors interacted with each other and with the spectator in detail and very poetically. Moreover, Kandinsky was a synaesthete, i.e. he could ‘hear colors’ and ‘see sounds.’
