The only reason I used the term "tried" is because it is a repaint and it appears to be shades of brown that look like shades of brown I have seen in other pre-54 Suburbans. Those colors might be a good match - it looks like the restorer tried to stay with original colors. I wonder if the colors were computer matches (a la PPG Prophet) or based on original codes (or matching modern off-sets).

I'd also like to know the name of the original exterior color (Seacrest Green?) and how the modern formula for it was found.
