1956 Eldorado Rubber Floor Mats - Reproductions - Color Info needed

[www.eldorado-seville.com]

A friend of mine is restoring his 56 Biarritz and could not find rubber floor mats.
So he decided that he will have them reproduced. He will have exact reproductions made.
Luckily a very nice 56 Biarritz owner borrowed him a nice set of mats to make this possible.
As tooling costs for the rubber extrusion and the chrome stripes will be quite a lot of money, he will have about 10 sets made for each of the 4 available colors. (Actually the tools are already made and production could already begin)
The problem he has now is how to find the correct colors for the rubber… (Black is easy... ;-) )
Do you have pictures of the various floor mats or an idea which modern paint code would match?

thanks in advance!
