Research about Peter Saville and Trevor Key's work on 'dichromat', a technique created by them. Dichromat allowed these two designers to manipulate color in images before photoshop made it all easier. Many LP and CD covers were born from this technique, but it still remains a secret.
This is an experimental book, which includes visual interpretations and speculations on the (very little) existing information about how the techique works.
