Hi johnnyforkball !
To the best of my knowledge, the only color you can get is grayscale burned on a color label surface.
Currently, the LightScribe Technology only does grayscale.
You can only darken part of the surface of a disk with a colored label surface and leave part of it un-burned and leave the surface color.
The best I know, no disk or drive manufacturer has solved the color problem.
The color choice is meant to change the PREVIEW so you can see what the label will look like on Color Media.
