Pepper was a member of staff in the Media Art Department there and Krantz had been invited by Dieter Jung, Professor for Media Art and head of the holography unit, as a research fellow.

They collaborated on a series of experiments together in the hope of developing new work and establishing a system for artists to use colour mixing in a direct and spontaneous way. The results were a number of experimental pieces of which Colour Study was one. The work which came out of this very fruitful working relationship has become known as the "Art of Collaboration Series", and been exhibited in group and solo exhibitions around the world.

Although their aim was to produce visual results, they also wanted to make their new techniques available to a wider audience and so wrote two papers, which were presented at international conferences. One concentrated on the technical aspects, explaining how the pieces were produced, the other looked at collaboration and aesthetics. Both are published by SPIE.
