Curator, Ann Temkin: We've borrowed for the exhibition a small set of the many collages that Judd made as he was thinking through the multicolored aluminum works. And he would make these collages out of the little color chips from the RAL color charts that he worked with.
RAL is a German-derived system that set up universal color across industries. So, for example, if you needed traffic signs for all of the highways in a certain country, that all of those traffic signs would be the exact same green. He liked the idea that here was this set of a couple hundred absolutely ready-made colors that you would pick from. They were colors that didn't involve any kind of romantic association with genius or creativity.
