"Of course, that is correct. The green markers couldn't possibly have an effect. Not if you believe that it works on principles stated by the manufacturer; or other skeptics. When it comes to avant garde audio inventions, here's a secret I will share with you tonight: manufacturers don't always know how their products work. They don't always get it right. The good people at "CD Stoplight" tried to, bless their souls. But then their hypothesis was easily discounted, when people pointed out that the green color cannot have an effect upon the wavelength used by lasers. Let alone affect the 1's and 0's, or the "bit-perfectness".
The reason the Green Pen works is because, although the nominal wavelength of a CD laser is 780 nm, near infrared, part of the spectrum is in the visible red portion of the spectrum. The beam of the laser is not monochromatic. The CD laser has a bandwidth of 100 nm or so. It's just a simple device with two filters. The reason it has visible red content is for safety reasons. And since green or blue green is the absorbing color for red, the sound is improved by the Green Pen since part of the scattered laser light will be absorbed.
But things have got better and now we can absorb not only the 30% or so of scattered light that's visible red but also the other 70% that's invisible light above 700 nm. It just a little time to solve the problem. Difficult problems we solve quickly the impossible ones take a little longer.
As for the PWB purple pen it works on LPs too so by inspection it has nothing to do with the CD laser.
