The project began when John decided that the manufactured pastels available on the market broke easily, were not consistent in texture and did not mirror his colour vision. For several years he worked on methods of production, colour sequences and the texture of his pigment mixtures.
In 1987 he decided to offer the results to fellow pastellists. He and Kate took the original range of colour sets (then just 117 pastels!), and the kitchen dresser, to an art materials show in London. To their surprise there was an immediate interest.
