The ones I created are Pantone coded - or at least as close to a match as they could be, based upon the reference I was using at the time. Photography can be notoriously fickle when it comes to accurate color, so bear that in mind. Also, the actual printed decals often faded over time, and in many instances there would be tremendous variation in color even in a single print run. I can't say whether or not the contributions of others have been Pantone coded, though.
