I've just bought an airbrush and want to get into repainting, I'm mainly interested in movie accurate or official canon paint schemes. However I can't find any information on FFG colour matches or anything.

What I'd like to start is a thread where people can post their canonical repaints with brief lists of the colours and brands used and how they got the effect..

Here are some painting threads - the info you seek may be in there or are you looking for a list by ship perhaps?

Like:

T-65 Wing:

official name gray

official name red

official name black

etc...
