Recently people have been finding that after the map pack was available, including 3 maps and a brand new zombie map, that they could change the color of their clan tag. It’s a pretty cool feature, like the PS3, by defining a color in your clan tag you can change its color.

Known Colors:
Red
Cyan
Yelw
Grn

These are the only ones I know of at the moment, I will be sure to update you once there are more colors available. I’ll check the PS3 at my mates house to find out what colors he knows!
