In 1966, artist Gerhard Richter began painting simple, uniform grids of colored rectangles or squares on a white background.

 

In the ’70s, Richter stopped using paint chips as source material, and began selecting colors at random, giving himself even less control over the painting’s composition.

 

I took his finished charts, cut them up, put them in a box and selected the chart which dictated the colors I would be restricted to use.
