I was researching some paint codes and came across a paint company who do sets of colours for specific aircraft. In their description they include all the paint codes. I made a word document of most of them, and thought you might find it useful, so have attached it here.
The paint codes are really useful for then buying model paint, if you want to use a conversion chart like these websites:
