The problem I ran into with several paint jobbers was that they had no interest in mixing paint without a valid paint code...one even suggested they had the very scanner that you're talking about, and on the next visit a few days later, said that thing never worked...I even found those very same paint chips at one supply store, but they could not figure out the correct recipes for the colors I had found...we surmised that the recipes were in a file folder in a box in a warehouse somewhere and the guy who knew where they were had retired, cuz the supply house could not get any help from the manufacturer. One thing the suppliers all agreed on was trying to get those vintage tints from a vintage paint supplier online, or find a similar color that was still available...since I am not at the final paint stage, I have not pursued this to satisfaction yet
