As I remember it the theory was that by running a marker pen round the edge of a CD, the internal reflections of the laser within the disc were somehow affected and this reduced the bit error rate. This in turn reduced the amount of error correction needed and thus gave better sound. Green has something to do with the laser wavelengths used but my knowledge of historical Hi-Fi myths doesn't go into that much detail!
