During the 1970s and 1980s, Suga barely used any color paint in his work except for black, white, or grey, as he preferred to let the natural color of wood or other materials stand on its own. It was in the early 1990s that he began to explore the use of other colors, also taking an increasingly expressionistic approach to the application of paint. The orange paint in this work is specifically a type of anti-rust paint, which he experimented with before expanding to the use of more conventional artist paints. The protruding coils at the edge imply an equivalence or continuity between two-dimensional painted surface within the “frame” and the three-dimensional materials protruding beyond it.
