I have never messed with the colors, as I don't want to play around with it and have to keep flashing my bios to get it looking the way I want.
I looked on xbtool when I first used it for a "preview" option and <of course> didn't find it. I sort of dropped it and left it at that.
I think that would be the best addition to xbtool in quite some time, and open up color modded bioses to another group of people out there (too lazy to try process of elimination...)
