After 5 years of owning the profiler I just recently noticed the ability to change the color of the screen. I've only been using Rig Manager for about a year, prior to that all adjustments have been made on the rack unit itself. I tried a few different colors but it threw me off and I had a difficult time navigating the menu's, when I got it back to default I've not touched it since.
Some people might find this type of filter useful and enjoy customizing colors, but apparently color options overload my feeble grey matter circuits : )
The Kemper II will have a color screen. Just buy a new one. 
LOL!!
I don't feel like buying a new one, and from here a Kemper 2 is made, I think I'll retire
