It seems that the team colors are going to be gametype-specific in Halo 4.
Slayer: Red v. Blue
Flag: Green v. Yellow
Oddball: Purple v. Orange

I personally don’t like this much, but what do you guys think?
UPDATE
From the 7.18.12 Bulletin:
> CTF looks to be Yellow vs. Green and Oddball looks like Purple vs. Orange. Any reason behind this? - Xx Overkill VR
>
> Those are the current colors, based on stuff like map palette content, color blindness, all sorts of reasons, but they’re also simply the colors from the build that was ready at Comic-Con, so don’t be shocked if that changes.
Judging by this, team colors may not only be gametype-specific, but also map-specific. Interesting…
