Alright msycamore and timdiggerm, how would you determine the most accurate source?

I've got to base these colors on something. First thing I'm basing it on is what these things actually look like, and stormtrooper armor is white. Correcting for that, it seems that the two most accurate sources are on the bottom, and I'll use both when finalizing the color. Neither the frame scan nor the Senator photo look all that dubious to me.

I'm sorry that this stuff isn't interesting to everyone, but I don't comment in other people's threads about how their type of project just doesn't interest me. If I'm interested, I comment. If I'm not, I don't.
