I have heard that the different color dyes used have an affect on quality and shelf life. What do you use?
When you look at the bottom of a CD-R, it generally appears blue, green, or gold regardless of the color of the label area on top. The color you see is a combination of reflective material in the disc and the dye layer of the CD. CD-R recorder technology uses a high-intensity laser to create a data pattern in a layer of dye manufactured in the disc. The dye layer is usually made with one of three organic dyes cyanine for green discs, phthalocyanine for gold discs, and azo for silver/blue discs. In repeated tests by the Optical Storage Technology Association and CD-R manufacturers, no correlation has been found between the color of the dye used in the CD-R disc and the quality of the CD-R media. To a CD reader/writer, there is no visual difference among the three, as all are opaque to the laser at the required frequency for reading and recording. All meet the specifications for the dye layer as described in the Orange Book, Part II the primary specification for CD-R technology, as devel
