Nothing is wrong with the vinyl or the print itself, but these rolls were a color misprint and are more much more muted than their fabric counterparts.
In the second photo you can see the two colors side by side.
If you order vinyl from the regular librarian, listing it will be more like the fabric color. If you order vinyl from this listing it will be as shown, and the mroe muted back color. This color cannot be replicated as it was a printing error originally.
