I've noticed in the recent batch of screenshots that the colours the ships fly don't stay the same, this applies to all races but the Vasari are a good example. All the shots can be found here.
Link(I would post them in individual links but it seems the forum HTML has become somewhat garbled when it comes to posting links, unfortunately this means there's some digging to be done to find the shots in question but there are definitely Vasari ships flying in Red, Orange and Blue)
Are these changes environment based or are the team colours in a skirmish type scenario?
