What's the deal with coloring CD's and/or tray mechanism

The intriguing thing about the whole Green Pen and painting the outer edge of the CD or the CD tray with green ink, the complementary color of red, thing is that the CD laser is essentially invisible light in the near infrared part of the spectrum. Thus theoretically at least green or any other color should have no affect on the sound since infrared light, being invisible, has no complementary color that could absorb it (before it makes its way into the photodetector).

far better tweak is to draw green rings on your power cables

Hey, mods! Randy’s stalking me again!

If edge supposed to reflect infrared then it should be gold marker, but if it supposed to kill reflections it should be black.  Green doesn't make sense.

"If edge supposed to reflect infrared then it should be gold marker, but if it supposed to kill reflections it should be black. Green doesn’t make sense."

green makes sense if you if you want to absorb red light. Reflecting any light doesn’t make sense since reflections will make their way to the photodetector. The scattered light completely fills the transport compartment.
