I agree that we are not going to get definitive colours - we shouldn't even try because that is nonsense. I think that as long as we can agree on sets (or multiple sets) that seem acceptable, it would be a good start.
I also agree with Clint when he says weathering is better achieved by adding extra weathering layers. (I do get lazy and modify the base paint layer quite often though

).
As for John's 70/71 swatch, it looks good to me. Would the Luftwaffe addicts mind posting some pictures of aircraft painted with these colours? Come on, guys: we know you're lurking and we know you have the correct pictures.

Don't force me to give names.
The ideal would be new or fairly new aircraft. This could help us IMHO.
