With medieval glass...I don’t think so.
Apparently, most of the stained glass was 19th century work, fitted into the existing Medieval patterns, because of earlier restorations.
Obviously it would not be with medieval glass, but I imagine that the colors can be reproduced today. I will ask a stained glass restorer I know. I know when my grandfather created the stained glass windows for the Indiana State Library he produced a number of different colors of glass for the work. Then again, maybe someone has a stash of unused ancient glass.
