Create an abstract background with muted colors and rigid shapes. The image should appear static and lifeless. The colors should be dull and monotonous, with a lack of contrast. The shapes should be geometric and angular, with sharp edges and clearly defined boundaries. There should be no sense of depth or dimension in the image, and all shapes should be evenly spaced and uniform in size. The overall composition should be unbalanced and visually uninteresting, with no clear focal point. The image should evoke a feeling of boredom and stagnation.
