This by Piero Dorazio is a rare work with a powerful visual impact for the reasons we explain. The canvas, divided into horizontal bands, is painted over its entire surface. The brushstrokes are oblique and with the same inclination. Dorazio used both primary colors and a huge amount of shades of primary colors. Stroke sizes are small in the lower right corner and gradually increase to the upper left corner. The colors are light and bright in the lower right corner and then degrade to darker and less bright colors in the upper left corner. We don't know if Dorazio wanted to give some optical effect to this work, he certainly forces the viewer to dwell on every single part of the work and to involve him emotionally.
