Thanks for the replies.
So I looked around a bit more in the OM and sop's. The only mention about FMA calls in the OM I can find with, is an example regarding armed modes that they should be called with their color.
And it gives a clear example. ''G/S BLUE'', ''LOC BLUE''. It then goes on about active modes being called out without their color, and gives a few more examples. And goes on about the usual stuff like challenging when nothing or wrong thing is said etc.
I guess this is the answer for my own question and we can close this discussion. I do not at all like to be such a pedantic f*ck. But when constantly being challenged about little things (some were good hints though), its gonna spark my interest aswell.
