I don’t remember precisely, the name of the first painting I saw, of Paul Klee’s rough grids of colored squares. Here are some of Klee’s paintings in the style to which I refer: Ancient Sound, Abstract on Black; Coming to Bloom; Altimetry of Stripes; Rhythmical, Glass Facade.
I looked for patterns of color, but could find none. I could not find any rational (i.e., mathematical series) or aesthetic reason for the ordering of the array. I was frustrated. Perhaps the order of colored blocks of paint was random and the exact point of the composition was to make the viewer’s eyes search nonstop for order.
Here is a rectilinear array that I painted:
I had planned to add more to this composition, to which I applied latex masking prior to painting. However, the colored squares and rectangles provided the only visual elements needed, and I abandoned the white spaces except those that I made into the horizontal and vertical lines of the grid.
