Green or turquoise around the outer edge and black around the inner edge is a good place to start but is not a universal solution since the color(s) of the CD label influences the sound. Black should always be used around the inner edge. Mercury Living Presence CDs (black and white label), for example, respond poorly (worse sound) to green around the outer edge but respond well to red around the outer edge. Go figure. For most CDs the color purple (violet) - as opposed to magenta - around the outer edge works very well.But things are more complicated and quite a bit more can be done with coloring CDs. The way light waves, including stray scattered light waves, interact within the player determines how much scattered light enters the photodetector as noise. So additional cancellation and reinforcement using colored pens can be quite audible. But where should these additional colors be applied? Answer coming soon.
Yellow (around the outer edge) is an interesting color for Blu Ray discs since yellow is the complementary color for the laser used to read Blu Ray discs.
The big reveal - The use of colors in close proximity to the laser and photodetector can greatly influence the sound. I will post a photo later today illustrating a general approach to applying colors to the data side of the CD near the spindle hole, in the 1/4 inch diameter ring visible just before the start of the data.
