I found my colour code on my badge under the hood (as you mentioned)! Mine colour is Garnet and the code is 512. I can only assume that they're all 3 digets, but who knows!? My colour code was also in my books, all the way in the back. Call M.B. and ask to get a copy of your window sticker (assuming you don't have one). That might have the colour code. Of course you might just want to call your local dealership too, to try to find a 1994 colour chart on Ebay.

Hope one of these ideas help...but I'd be willing to bet that you've already read your colour, you just haven't realized it yet!

Good luck!
