Thanks Retropin for the explanation.  Without knowing the process or understanding it I thought the CPR reply was pretty weak, dismissive and treated the customer as one who should be grateful.  Clearly they know the colour match is poor so they should be saying that and making their excuses on the sales and gallery page, not presenting it after purchase.  They have this information and it should be presented to enable would be purchasers to make a fair decision.  The purchaser may not have an original to compare with, they may think someone selling a "reproduction" has indeed reproduced it.

I've never bought anything from them, but it seems they have a few products not up to scratch and are getting a history of poor attention to detail.  I'd beware.
