LeWitt demonstrated 34 different combinations of lines rendered in four colors. However, grid generation process was neither entirely predictable nor free from errors, as he was well aware. He said in 1974 "I've done a lot of things with drawings and prints, using color in a theoretical way. There were four parts of the drawing: four lines in four directions. You know, vertical, horizontal, diagonal, both ways. And then you could use four colors: the three primary colors plus black. So I've done things with colors, but you can't add color to these things without making it a little absurd and diminishing".
