theproblem will probably be that it's already been shipped and packaged. I suspect they'll potentially add in an update?
This is where NECVARs come into play. They could change the numbers right now and when you start the game while your system is online, you'd already have the new numbers in place.
So they'd just have to change the colour-code and
dang!, you're on orange and cyan instead of red and blue.
But as they have completely remappable controls (which does allow disabled people to play the game better), I doubt they've forgotten about colour-blind people.
