it won't really make it brighter at all, just a different color that may be easier for you to see, based on your preference. personally, when i'm dyeing discs, i like to start with white or clear discs to have a clean template to dye on.
So here's a pic of the Orion LF and a pic. of an Orange Buzzz that suits my color tastes. Could dyeing OLF the right color orange have this drastic of an affect on the color?
