American Escort Fighter Formation Details

[Kurtl12]

Hello to everybody,

Looking for detailed information regarding Escort Fighter Formations during 1944. I have some rough information about the Flight codes.
Is it right that each flight had to consist of 4 planes, each squadron about 4 flights? Was the position of for example the red flight always the first, followed by green on the left hand wing side?

If someone had position 2 in yellow flight what does that mean? Was he flying on left wing or right wing side of the flight leader?

What color name was that one of a fifth flight? I know red, green, blue and yellow flight. Were there any other?

Is there a document available which shows how it actually was meant somewhere on the net?

Thanks for any help in advance.
