I am a bit of a novice at this myself but ran into a problem a while back when the PAL/NTSC were changed accidentally.
My general comment is that the game is not normally the problem when it comes to this issue as xbox games only have 1 format that I am aware of. It is the system settings that changes from PAL to NTSC to allow the game to work sending the signal to the TV in whichever format you need depending on where you live.
In my case I was not able to see the screen well enough to make the switch back from PAL to NTSC & needed a boot disc to allow me to change the setting. That worked fine & the tutorial is available. The boot disc file is available from the usual places, if that is needed but yours seems to be a color issue & may not be related to the PAL/NTSC settings at all.
If you are going to try changing the PAL/NTSC settings in the on your xbox anyway then get the boot disc first as changing them back without it could be a major hassel.
