I think that EDN looks pretty good too, what was the mix?
The transfers match well too, if you painted over them it's very neatly done.
Re the 'Guard' image - I agree with Achill, the 6021 looks closest, neat 216 looks a bit dark
Again, sorry to be repetitive, I don't think one should be too hung up about official specifications, what a colour looks like in service on an actual coach at some distance is the main thing surely. The 'Quiet Man' EDN looks a good deal lighter than 216, or is that my eyes, or 1950's colour film?
