Interesting. The IPDB shows the numbers as black outlined with a white middle. Furthermore, it shows the area you have painted brown should be red. Also the letters are nothing like yours, but you may just be doing a test look-see.
Anyway, you could make a waterslide with white decal and a black outline. If you wanted it to look original. But it seems like you are already off the reservation with the brown, so ... do whatever you like, I guess.
