Here's a pretty good list of color codes:

On my metal plate above the radiator, my color code is in the lower left corner, eg, my plate says "01 040 F". My color is 040 black. the 01 might be the first paint in a 2 color car, the F probably is the code for the company that manufactures the paint. I saw a list once, but can't lay my hands on it now.
Hope this helps.
