Pantone Billard Balls

I was inspired by the "Rubitone" of Ignacio Pilotto and the Pantone iPhone cases when I had this idea. I noticed that billard balls almost have the same structure as the color charts.

The numbering/colors of the balls and the pantone color chart do not really fit together, so I just took some random colours.

The main thing was created in Illustrator, the finishing in Photoshop.
