Hi ANDREW!
I do not know if you has ever heard about the 2 volumes intittled: "Aircraft of the Luftwaffe Fighter Aces" by Bernd Barbas. It contains a lot of photographs and schemes of camouflage. Both are awesome and I fully recommend...there are some color photographs and artwork also ( profiles ).
See here:

I also recomend this site:

Hope it will be of help.
