Making use of many design principles

Source: Kazumasa Nagai Poster Life 1957-2014, from 1973

     This image displays many of the design principles and concepts we have been learning about. Rhythm can be seen in the repetition and rate of change in the wavy lines. Gradation of the hot and cool colors creates an alternating rhythm. Balance is shown in the approximate symmetry displayed vertically. Emphasis on the circular shape based on warm color, overlap, and size. Depth is seen at the focal point of the circular shapes based on size, color, gradation of line weight. Overall this post makes little use of variety.
