I have the same question/issue with a set of Bad Cats decals I bought from ClassicArcades on Ebay. I've spotted issues with CA's products before, but in this case I thought the decals they were selling were the same as those from PPS! Same stock image and same description, both refer to "Next Gen, and the CA listing even said "licensed" so I felt safe and took the plunge during the ebay 20% off frenzy.
Well, the color on this set, while not as horrifically "off" as that Whirlwind one, is still not correct to me. Unfortunately I need to pose a better photo but what is obvious is that the original decals were a "hot" flourescent orange (as seen under hinges, rails, etc). The replacement decals are rather dull with no "pop" at all. They don't quite match the painted head I have either, but are close enough to excuse...
I will probably try to get a better photo later. I'm not sure if I should return these or not. There was some controversy when the BC decals were released a few years ago and Rick supposedly corrected them. But I'm probably out of luck since I bought these from CA....
