The fun thing is that the show has a colored pencil connection!
It is a show based on one small self-portrait done in soft-ground etching - a medium I am not familiar with. Here is a description of his process from the BMAC website:
Placing a piece of paper over the soft, waxy “ground” that covered each of twelve different metal plates, Close used a different colored pencil to make scribbled drawings on each plate. When he lifted the paper from each plate, some of the waxy ground pulled away, leaving bare metal where the pencil had made its impressions. Next he immersed the plate in a bath of acid that etched only the bare metal exposed by the drawing.
Close then inked each plate with a color corresponding to a different one of his twelve colored pencils. He printed each plate three times, creating a plate proof (a print with a single color), a progressive proof (a print showing the progression of the image as each color was added), and the final print (the accumulation of all the colors).

Although the end result is ink and not colored pencil, it remarkably "looks" like colored pencil. The show is set up with a finished proof that is numbered and signed as you walk in, and then going around the small room, a finished proof alternates on the wall with each color printed alone in between, so the viewer can have a look into the process. Each color that Close used was bright, but at the end they created more muted tones when the eye visually blends them together. The result reminds me of the circulism work of Maggie Toole since his scribbles are so controlled.

At the top of the brochure is the finished print and if you scroll down to the second page you'll see the original colored pencil drawing that created the print with the corresponding Prismacolor numbers written below. To any colored pencil geek (a club with which I belong) it is incredibly exciting to see Chuck Close write these numbers to which I can identify the colors! :)
