Hi there, one of our customers that we have sold westwood decals to recently told me he had been in contact with westwood and they told him the original RAL paint codes. He's created a thread on here, this is what he said
@Toma 'I have information that may be useful to others.
The correct colour is RAL2002 confirmed in the company and all the rest is not black, but RAL 7021'
It is a grey colour I believe, most paint companies should be able to mix both colours for you but someone on here may know a good match.
