I'm getting ready to paint the cab on a '53 3800 we have been working on forever. I'm not concerned with a super accurate color for the interior, but want to be close and use good quality paint. The original paint I can see is kind of a silvery light brown with some metallic in it. I see Jim Carter sells a color they call "semi flat brown", classic parts sells one they call "champagne". Is one of these better than the other or closer to original? Is there a better source? If possible I'd rather get something one of the vendors has rather than try to get something matched by our local paint supplier just for simplicity.
