Heres a sheet for Waffenfarbe for German WWII troops I have on my computer. It's specified for SS, but most of it is the same for most branches. With the exeptions of Himmler's Staff and such ones.
I post this because all the different colour can cause confusion by many, and for new guys to learn such a vital thing when painting German WWII troops.
If any of the other experts would shoot in something, feel free! I hope to get as much, and as correct information as possible, and will edit when I get more iformation.
Hope this helps!
