as for manufacturers putting green on the CDs, its an added cost. that right there makes it verboten.

most manufs will do anything to shave costs. as for myself, i found it to be effective sonically but too much of a PIA to green them. so it goes.

the sum of green and red is black which would reduce by a wide margin, the reflected/refracted scattered laser light within the cd itself. the green on the edge absorbs the stray laser light.
